Source/JavaScriptCore:

This part of the merge delivers roughly a 2% across-the-board performance
improvement, mostly due to immutable property inference and DFG-side GCSE. It also
almost completely resolves accessor performance issues; in the common case the DFG
will compile a getter/setter access into code that is just as efficient as a normal
property access.
        
Another major highlight of this part of the merge is the work to add a type profiler
to the inspector. This work is still on-going but this greatly increases coverage.

Note that this merge fixes a minor bug in the GetterSetter refactoring from
http://trac.webkit.org/changeset/170729 (https://bugs.webkit.org/show_bug.cgi?id=134518).
It also adds a new tests to tests/stress to cover that bug. That bug was previously only
covered by layout tests.

    Replace Identity with Check instead of Phantom. Phantom means that the child of the
    Identity should be unconditionally live. The liveness semantics of Identity are such that
    if the parents of Identity are live then the child is live. Removing the Identity entirely
    preserves such liveness semantics. So, the only thing that should be left behind is the
    type check on the child, which is what Check means: do the check but don't keep the child
    alive if the check isn't needed.

    This removes the old local CSE phase, which was based on manually written backward-search 
    rules for all of the different kinds of things we cared about, and adds a new local/global
    CSE (local for CPS and global for SSA) that leaves the node semantics almost entirely up to
    clobberize(). Thus, the CSE phase itself just worries about the algorithms and data
    structures used for storing sets of available values. This results in a large reduction in
    code size in CSEPhase.cpp while greatly increasing the phase's power (since it now does
    global CSE) and reducing compile time (since local CSE is now rewritten to use smarter data
    structures). Even though LLVM was already running GVN, the extra GCSE at DFG IR level means
    that this is a significant (~0.7%) throughput improvement.
            
    This work is based on the concept of "def" to clobberize(). If clobberize() calls def(), it
    means that the node being analyzed makes available some value in some DFG node, and that
    future attempts to compute that value can simply use that node. In other words, it
    establishes an available value mapping of the form value=>node. There are two kinds of
    values that can be passed to def():
            
    PureValue. This captures everything needed to determine whether two pure nodes - nodes that
        neither read nor write, and produce a value that is a CSE candidate - are identical. It
        carries the NodeType, an AdjacencyList, and one word of meta-data. The meta-data is
        usually used for things like the arithmetic mode or constant pointer. Passing a
        PureValue to def() means that the node produces a value that is valid anywhere that the
        node dominates.
            
    HeapLocation. This describes a location in the heap that could be written to or read from.
        Both stores and loads can def() a HeapLocation. HeapLocation carries around an abstract
        heap that both serves as part of the "name" of the heap location (together with the
        other fields of HeapLocation) and also tells us what write()'s to watch for. If someone
        write()'s to an abstract heap that overlaps the heap associated with the HeapLocation,
        then it means that the values for that location are no longer available.
            
    This approach is sufficiently clever that the CSEPhase itself can focus on the mechanism of
    tracking the PureValue=>node and HeapLocation=>node maps, without having to worry about
    interpreting the semantics of different DFG node types - that is now almost entirely in
    clobberize(). The only things we special-case inside CSEPhase are the Identity node, which
    CSE is traditionally responsible for eliminating even though it has nothing to do with CSE,
    and the LocalCSE rule for turning PutByVal into PutByValAlias.
            
    This is a slight Octane, SunSpider, and Kraken speed-up - all somewhere arond 0.7% . It's
    not a bigger win because LLVM was already giving us most of what we needed in its GVN.
    Also, the SunSpider speed-up isn't from GCSE as much as it's a clean-up of local CSE - that
    is no longer O(n^2). Basically this is purely good: it reduces the amount of LLVM IR we
    generate, it removes the old CSE's heap modeling (which was a constant source of bugs), and
    it improves both the quality of the code we generate and the speed with which we generate
    it. Also, any future optimizations that depend on GCSE will now be easier to implement.
            
    During the development of this patch I also rationalized some other stuff, like Graph's
    ordered traversals - we now have preorder and postorder rather than just "depth first".

    [ftlopt] Move Flush(SetLocal) store elimination to StrengthReductionPhase

    I'm going to streamline CSE around clobberize() as part of
    https://bugs.webkit.org/show_bug.cgi?id=134677, and so Flush(SetLocal) store
    elimination wouldn't belong in CSE anymore. It doesn't quite belong anywhere, which
    means that it belongs in StrengthReductionPhase, since that's intended to be our
    dumping ground.
            
    To do this I had to add some missing smarts to clobberize(). Previously clobberize()
    could play a bit loose with reads of Variables because it wasn't used for store
    elimination. The main client of read() was LICM, but it would only use it to
    determine hoistability and anything that did a write() was not hoistable - so, we had
    benign (but still wrong) missing read() calls in places that did write()s. This fixes
    a bunch of those cases.

    [ftlopt] Infer immutable object properties
    https://bugs.webkit.org/show_bug.cgi?id=134567
    
    Reviewed by Mark Hahnenberg.
            
    This introduces a new way of inferring immutable object properties. A property is said to
    be immutable if after its creation (i.e. the transition that creates it), we never
    overwrite it (i.e. replace it) or delete it. Immutability is a property of an "own
    property" - so if we say that "f" is immutable at "o" then we are implying that "o" has "f"
    directly and not on a prototype. More specifically, the immutability inference will prove
    that a property on some structure is immutable. This means that, for example, we may have a
    structure S1 with property "f" where we claim that "f" at S1 is immutable, but S1 has a
    transition to S2 that adds a new property "g" and we may claim that "f" at S2 is actually
    mutable. This is mainly for convenience; it allows us to decouple immutability logic from
    transition logic. Immutability can be used to constant-fold accesses to objects at
    DFG-time. The DFG needs to prove the following to constant-fold the access:
            
    - The base of the access must be a constant object pointer. We prove that a property at a
      structure is immutable, but that says nothing of its value; each actual instance of that
      property may have a different value. So, a constant object pointer is needed to get an
      actual constant instance of the immutable value.
            
    - A check (or watchpoint) must have been emitted proving that the object has a structure
      that allows loading the property in question.
            
    - The replacement watchpoint set of the property in the structure that we've proven the
      object to have is still valid and we add a watchpoint to it lazily. The replacement
      watchpoint set is the key new mechanism that this change adds. It's possible that we have
      proven that the object has one of many structures, in which case each of those structures
      needs a valid replacement watchpoint set.
            
    The replacement watchpoint set is created the first time that any access to the property is
    cached. A put replace cache will create, and immediately invalidate, the watchpoint set. A
    get cache will create the watchpoint set and make it start watching. Any non-cached put
    access will invalidate the watchpoint set if one had been created; the underlying algorithm
    ensures that checking for the existence of a replacement watchpoint set is very fast in the
    common case. This algorithm ensures that no cached access needs to ever do any work to
    invalidate, or check the validity of, any replacement watchpoint sets. It also has some
    other nice properties:
            
    - It's very robust in its definition of immutability. The strictest that it will ever be is
      that for any instance of the object, the property must be written to only once,
      specifically at the time that the property is created. But it's looser than this in
      practice. For example, the property may be written to any number of times before we add
      the final property that the object will have before anyone reads the property; this works
      since for optimization purposes we only care if we detect immutability on the structure
      that the object will have when it is most frequently read from, not any previous
      structure that the object had. Also, we may write to the property any number of times
      before anyone caches accesses to it.
            
    - It is mostly orthogonal to structure transitions. No new structures need to be created to
      track the immutability of a property. Hence, there is no risk from this feature causing
      more polymorphism. This is different from the previous "specificValue" constant
      inference, which did cause additional structures to be created and sometimes those
      structures led to fake polymorphism. This feature does leverage existing transitions to
      do some of the watchpointing: property deletions don't fire the replacement watchpoint
      set because that would cause a new structure and so the mandatory structure check would
      fail. Also, this feature is guaranteed to never kick in for uncacheable dictionaries
      because those wouldn't allow for cacheable accesses - and it takes a cacheable access for
      this feature to be enabled.
            
    - No memory overhead is incurred except when accesses to the property are cached.
      Dictionary properties will typically have no meta-data for immutability. The number of
      replacement watchpoint sets we allocate is proportional to the number of inline caches in
      the program, which is typically must smaller than the number of structures or even the
      number of objects.
            
    This inference is far more powerful than the previous "specificValue" inference, so this
    change also removes all of that code. It's interesting that the amount of code that is
    changed to remove that feature is almost as big as the amount of code added to support the
    new inference - and that's if you include the new tests in the tally. Without new tests,
    it appears that the new feature actually touches less code!
            
    There is one corner case where the previous "specificValue" inference was more powerful.
    You can imagine someone creating objects with functions as self properties on those
    objects, such that each object instance had the same function pointers - essentially,
    someone might be trying to create a vtable but failing at the whole "one vtable for many
    instances" concept. The "specificValue" inference would do very well for such programs,
    because a structure check would be sufficient to prove a constant value for all of the
    function properties. This new inference will fail because it doesn't track the constant
    values of constant properties; instead it detects the immutability of otherwise variable
    properties (in the sense that each instance of the property may have a different value).
    So, the new inference requires having a particular object instance to actually get the
    constant value. I think it's OK to lose this antifeature. It took a lot of code to support
    and was a constant source of grief in our transition logic, and there doesn't appear to be
    any real evidence that programs benefited from that particular kind of inference since
    usually it's the singleton prototype instance that has all of the functions.
            
    This change is a speed-up on everything. date-format-xparb and both SunSpider/raytrace and
    V8/raytrace seem to be the biggest winners among the macrobenchmarks; they see >5%
    speed-ups. Many of our microbenchmarks see very large performance improvements, even 80% in
    one case.

    [ftlopt] DebuggerCallFrame::scope() should return a DebuggerScope.
    <https://webkit.org/b/134420>
    
    Reviewed by Geoffrey Garen.
    
    Previously, DebuggerCallFrame::scope() returns a JSActivation (and relevant
    peers) which the WebInspector will use to introspect CallFrame variables.
    Instead, we should be returning a DebuggerScope as an abstraction layer that
    provides the introspection functionality that the WebInspector needs.  This
    is the first step towards not forcing every frame to have a JSActivation
    object just because the debugger is enabled.
    
    1. Instantiate the debuggerScopeStructure as a member of the JSGlobalObject
       instead of the VM.  This allows JSObject::globalObject() to be able to
       return the global object for the DebuggerScope.
    
    2. On the DebuggerScope's life-cycle management:
    
       The DebuggerCallFrame is designed to be "valid" only during a debugging session
       (while the debugger is broken) through the use of a DebuggerCallFrameScope in
       Debugger::pauseIfNeeded().  Once the debugger resumes from the break, the
       DebuggerCallFrameScope destructs, and the DebuggerCallFrame will be invalidated.
       We can't guarantee (from this code alone) that the Inspector code isn't still
       holding a ref to the DebuggerCallFrame (though they shouldn't), but by contract,
       the frame will be invalidated, and any attempt to query it will return null values.
       This is pre-existing behavior.
    
       Now, we're adding the DebuggerScope into the picture.  While a single debugger
       pause session is in progress, the Inspector may request the scope from the
       DebuggerCallFrame.  While the DebuggerCallFrame is still valid, we want
       DebuggerCallFrame::scope() to always return the same DebuggerScope object.
       This is why we hold on to the DebuggerScope with a strong ref.
    
       If we use a weak ref instead, the following cooky behavior can manifest:
       1. The Inspector calls Debugger::scope() to get the top scope.
       2. The Inspector iterates down the scope chain and is now only holding a
          reference to a parent scope.  It is no longer referencing the top scope.
       3. A GC occurs, and the DebuggerCallFrame's weak m_scope ref to the top scope
          gets cleared.
       4. The Inspector calls DebuggerCallFrame::scope() to get the top scope again but gets
          a different DebuggerScope instance.
       5. The Inspector iterates down the scope chain but never sees the parent scope
          instance that retained a ref to in step 2 above.  This is because when iterating
          this new DebuggerScope instance (which has no knowledge of the previous parent
          DebuggerScope instance), a new DebuggerScope instance will get created for the
          same parent scope. 
    
       Since the DebuggerScope is a JSObject, it's liveness is determined by its reachability.
       However, it's "validity" is determined by the life-cycle of its owner DebuggerCallFrame.
       When the owner DebuggerCallFrame gets invalidated, its debugger scope chain (if
       instantiated) will also get invalidated.  This is why we need the
       DebuggerScope::invalidateChain() method.  The Inspector should not be using the
       DebuggerScope instance after its owner DebuggerCallFrame is invalidated.  If it does,
       those methods will do nothing or returned a failed status.

    The enables exposing the call to setters in the DFG, and then inlining it. Previously we
    already supproted inlined-cached calls to setters from within put_by_id inline caches,
    and the DFG could certainly emit such IC's. Now, if an IC had a setter call, then the DFG
    will either emit the GetGetterSetterByOffset/GetSetter/Call combo, or it will do one
    better and inline the call.
            
    A lot of the core functionality was already available from the previous work to inline
    getters. So, there are some refactorings in this patch that move preexisting
    functionality around. For example, the work to figure out how the DFG should go about
    getting to what we call the "loaded value" - i.e. the GetterSetter object reference in
    the case of accessors - is now shared in ComplexGetStatus, and both GetByIdStatus and
    PutByIdStatus use it. This means that we can keep the safety checks common.  This patch
    also does additional refactorings in DFG::ByteCodeParser so that we can continue to reuse
    handleCall() for all of the various kinds of calls we can now emit.
            
    83% speed-up on getter-richards, 2% speed-up on box2d.

    [ftlopt] Reduce the GC's influence on optimization decisions
    https://bugs.webkit.org/show_bug.cgi?id=134427
    
    Reviewed by Oliver Hunt.
            
    This is a slight speed-up on some platforms, that arises from a bunch of fixes that I made
    while trying to make the GC keep more structures alive
    (https://bugs.webkit.org/show_bug.cgi?id=128072).
            
    The fixes are, roughly:
            
    - If the GC clears an inline cache, then this no longer causes the IC to be forever
      polymorphic.
            
    - If we exit in inlined code into a function that tries to OSR enter, then we jettison
      sooner.
            
    - Some variables being uninitialized led to rage-recompilations.
            
    This is a pretty strong step in the direction of keeping more Structures alive and not
    blowing away code just because a Structure died. But, it seems like there is still a slight
    speed-up to be had from blowing away code that references dead Structures.

    [ftlopt] If a CodeBlock is jettisoned due to a watchpoint then it should be possible to figure out something about that watchpoint

    This is engineered to provide loads of information to the profiler without incurring any
    costs when the profiler is disabled. It's the oldest trick in the book: the thing that
    fires the watchpoint doesn't actually create anything to describe the reason why it was
    fired; instead it creates a stack-allocated FireDetail subclass instance. Only if the
    FireDetail::dump() virtual method is called does anything happen.
            
    Currently we use this to produce very fine-grained data for Structure watchpoints and
    some cases of variable watchpoints. For all other situations, the given reason is just a
    string constant, by using StringFireDetail. If we find a situation where that string
    constant is insufficient to diagnose an issue then we can change it to provide more
    fine-grained information.

[GTK] Add support for user scripts to WebKitUserContentManager
https://bugs.webkit.org/show_bug.cgi?id=134738

Patch by Adrian Perez de Castro <aperez@igalia.com> on 2014-08-06
Reviewed by Carlos Garcia Campos.

Add support for user scripts, to complement the user style sheet
support already present in WebKitUserContentManager. Most of the
moving parts are already present, so this just adds a boxed type
for user scripts (WebKitUserScript) and the corresponding methods
to add and remove scripts from the WebKitUserContentManager.

Source/WebKit2:

* UIProcess/API/gtk/WebKitUserContent.cpp: Add a WebKitUserScript
boxed type and its corresponding methods and enums.
(toUserScriptInjectionTime): Needed to convert
WebKitUserScriptInjectionTime values into its WebCore counterparts.
(_WebKitUserScript::_WebKitUserScript): Added.
(_WebKitUserScript::referenceCount): Ditto.
(webkit_user_script_ref):
(webkit_user_script_unref):
(webkit_user_script_new):
(webkitUserScriptGetUserScript): Internal method to obtain the
boxed WebCore::UserScript value.
* UIProcess/API/gtk/WebKitUserContent.h: Add the new public API
methods.
* UIProcess/API/gtk/WebKitUserContentManager.cpp: Implement the
methods for adding and removing user scripts.
(webkit_user_content_manager_add_script):
(webkit_user_content_manager_remove_all_scripts):
* UIProcess/API/gtk/WebKitUserContentManager.h: Add the new public
API methods.
* UIProcess/API/gtk/WebKitUserContentPrivate.h: Add the definition
for the new private function.
* UIProcess/API/gtk/docs/webkit2gtk-sections.txt: Include the
new public methods in the API documentation.
