a4404f21d1 This patch adds support for sender-aware dispatch in Objective-C for the GNU runtime, when 
compiled with -fobjc-sender-dependent-dispatch.  This is used in AOP, COP, implementing object 
planes, and a few other things.

d20a03f308 This patch provides preliminary support for non-fragile instance variables on the GNU runtime. 
It currently requires a patches to GNU libobjc (and so is not enabled by default) which are currently 
being tested and reviewed by GNUstep before being pushed upstream.
This patch does not allow support for synthesized ivars, but does provide the infrastructure 
needed for supporting them.

b27c94199f This patch allows clang to generate code for declared properties on the GNU runtime. As with @synchronized, this requires some extra functions that are included with other libraries (not with the GNU runtime itself) and so will cause linker errors when these are not present.

078cd52297 This patch fixes two bugs in the GNU Objective-C runtime implementation. One is a case in rethrowing exceptions where the C types don't match correctly (I already sent this patch to Daniel Dunbar, who found the bug, so it may have already been committed). The other fixes the case properties so that the methods generated as property accessors are added to the class structure correctly.

b6e9eb6956 initial support for ObjC exceptions with the GNU runtime: 
"This patch is a first pass at adding support for exceptions for the GNU runtime.  There are a few limitations at present:

- @synchronized() is not yet supported at all.  gcc currently emits calls to runtime library functions that don't exist for this directive.

- Only id @catch statements are currently working.  This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.

- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

c06ce0f710 "This fixes message sends to super in a way that both works with real code and passes the test in the test suite. It also fixes a crash when using recent versions of GNU libobjc and compiling modules that do not contain any constant strings but do contain a declaration of the constant string class and possible some other corner cases (thanks to Pete French for providing me with a test case for that one)."

29bd76fd04 Eliminate the three SmallVectors in ObjCImplDecl (for instance 
methods, class methods, and property implementations) and instead
place all of these entities into the DeclContext.

This eliminates more linear walks when looking for class or instance
methods and should make PCH (de-)serialization of ObjCDecls trivial
(and lazy).

9fd114d577 Merge ivar access amongst the three runtimes. 
- For now, this means we are always doing the address computations by
   hand instead of constructing a proper GEP. Right now, however, this
   is less important than having fewer entry points to dealing with
   Objective-C interface layout.

66afeb5968 Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change. 
Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).

ffca3a21f1 Provide a new kind of iterator, the specific_decl_iterator, that 
filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.
