ObjectiveC. Remove warning diagnostic which checks
attribute on method declaration and implementation
match. This makes no sense. Most annotations are
meant for declarations only and one is for implementation.
This has been constant source of regresions and hackery to
get around special cases. I am removing this check.
Such checks must be done on a case by case basis and
when it makes sense. For example, it makes sense
for availability/deprecated and I will file a radar
for that. // rdar://15531984

Remove uninstantiable constructor from DeclTemplate.h

Patch by Kim Gräsman!

Laszlo Nagy and me both ran into the same issue with SpecIterator from DeclTemplate.h causing an error:

tools/clang/include/clang/AST/DeclTemplate.h:560:22: error:
      no matching constructor for initialization of 'SetIteratorType' (aka
      'FoldingSetVectorIterator<clang::FunctionTemplateSpecializationInfo,
      typename SmallVector<FunctionTemplateSpecializationInfo *, 8>::iterator>')
    SpecIterator() : SetIter() {}

(see e.g. http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-November/033642.html)

The problem is the SpecIterator default constructor which needs a non-existent SetIter default constructor. SpecIterator's default constructor is evidently dead code as any call to it would fail with the above error.

This patch removes it.

Change ObjCIntefaceDecl::lookupMethod() to have optional 'followsSuper' argument.

This enables a micro-optimization in protocol conformance checking
to not examine the class hierarchy twice per method.

As part of this change, remove the default arguments from lookupInstanceMethod()
and lookupClassMethod().  It was becoming very redundant.  For clients
needing the default arguments, have them use the full API instead of
these convenience methods.

Add back experimental attribute objc_suppress_protocol_methods (slightly renamed).

This is still an experimental attribute, but I wanted it in tree
for review.  It may still get yanked.

This attribute can only be applied to a class @interface, not
a class extension or category.  It does not change the type
system rules for Objective-C, but rather the implementation checking
for Objective-C classes that explicitly conform to a protocol.
During protocol conformance checking, clang recursively searches
up the class hierarchy for the set of methods that compose
a protocol.  This attribute will cause the compiler to not consider
the methods contributed by a super class, its categories, and those
from its ancestor classes.  Thus this attribute is used to force
subclasses to redeclare (and hopefully re-implement) methods if
they decide to explicitly conform to a protocol where some of those
methods may be provided by a super class.

This attribute intentionally leaves out properties, which are associated
with state.  This attribute only considers methods (at least right now)
that are non-property accessors.  These represent methods that "do something"
as dictated by the protocol.  This may be further refined, and this
should be considered a WIP until documentation gets written or this
gets removed.

Generate a marker token when entering or leaving a submodule when building a
module. Use the marker to diagnose cases where we try to transition between
submodules when not at the top level (most likely because a closing brace was
missing at the end of a header file, but is also possible if submodule headers
attempt to do something fundamentally non-modular, like our .def files).

clang-format: Prefer column layout if possible.

Add a severe penalty for not using column layout for braced lists. If
there are solutions with column layout, these are generally preferable
over bin-packed solutions.

Enable non-fragile ABI for the ObjFW runtime

The following patch enables the non-fragile ABI for the ObjFW runtime.

However, I noticed that it is not possible anymore to disable it with
-fno-objc-nonfragile-abi like it was before. I think this functionality should
be restored, but I guess this is not in scope for 3.4 anymore.
