Added TargetRegisterInfo::getRegPressureSetName.
Make sure the "synchronous breakpoint callbacks" get called before the thread plan logic gets invoked, and if they
ask to continue that should short-circuit the thread plans for that thread.  Also add a bit more explanation for
how this machinery is supposed to work.
Also pass eExecutionPolicyOnlyWhenNeeded, not eExecutionPolicyAlways when evaluating the expression for breakpoint
conditions.
Print <def,read-undef> to avoid confusion.

The <undef> flag on a def operand only applies to partial register
redefinitions. Only print the flag when relevant, and print it as
<def,read-undef> to make it clearer what it means.
If we discover all of the named structs in a module, then don't bother to
process any more Values.
[analyzer] Constify
[analyzer] Remove unused method.
[analyzer] Run remove dead bindings right before leaving a function.

This is needed to ensure that we always report issues in the correct
function. For example, leaks are identified when we call remove dead
bindings. In order to make sure we report a callee's leak in the callee,
we have to run the operation in the callee's context.

This change required quite a bit of infrastructure work since:
 - We used to only run remove dead bindings before a given statement;
here we need to run it after the last statement in the function. For
this, we added additional Program Point and special mode in the
SymbolReaper to remove all symbols in context lower than the current
one.
 - The call exit operation turned into a sequence of nodes, which are
now guarded by CallExitBegin and CallExitEnd nodes for clarity and
convenience.

(Sorry for the long diff.)
objective-c arc: With currnt documentation,
objc_returns_inner_pointer attribute can be applied to
methods only. Diagnsose otherwise, instead of
crashing. // rdar://11253688
[libclang] Don't set dylib load address to 0xe000000.

Per Greg Clayton:
libclang.dylib is trying to be smart and load itself at a valid address
to be able to load faster which would work for 32 bit systems,
bit won't make any difference on 64 bit systems.
It should either pick a better 64 bit address, or just let itself be loaded at zero.

Extraneous semicolon.
Register DAGUpdateListeners with SelectionDAG.

Instead of passing listener pointers to RAUW, let SelectionDAG itself
keep a linked list of interested listeners.

This makes it possible to have multiple listeners active at once, like
RAUWUpdateListener was already doing. It also makes it possible to
register listeners up the call stack without controlling all RAUW calls
below.

DAGUpdateListener uses an RAII pattern to add itself to the SelectionDAG
list of active listeners.
Make ISelPosition a local variable.

Now that multiple DAGUpdateListeners can be active at the same time,
ISelPosition can become a local variable in DoInstructionSelection.

We simply register an ISelUpdater with CurDAG while ISelPosition exists.
Revert r155241, which is causing some breakage.
ARM: tblgen'erate more NEON two-operand aliases.
Fixed some issues with symbolicating things. Fixed symbolication.add_module() to not use the resolved_path before we have tried to locate it. Fixed crashlog.locate_module_and_debug_symbols() to return true and false correctly.
Fix PR12599.

The X86 target is editing the selection DAG while isel is selecting
nodes following a topological ordering. When the DAG hacking triggers
CSE, nodes can be deleted and bad things happen.
ARM: tblgen'erate more NEON two-operand aliases.

VMUL and VEXT.
Method name change to avoid further conflicts when merging from ToT to branches/lldb-platform-work.
Added code to automatically load the libheap.dylib when ptr_refs, cstr_refs or malloc_info are called. If MallocStackLogging is enabled, then you can now use --stack to dump the backtrace of the code that allocated each malloc block.
Link with Foundation whenever -fobjc-link-runtime is used.  <rdar://10976177>

The check for excluding libarclite on i386 MacOSX should not apply to
Foundation.
