08a45257de Make the property accessor functions that take a ptrdiff_t actually take a ptrdiff_t instead of a long (should have no impact on any sane platforms, but win64 is not sane).

74186ab391 Access ivars with inbounds GEPs, even in -fwrapv. It's unlikely that
this can have any optimization effect, given the opacity of objects pointers,
but you never know.

cf7f66f16f objc IRGen for Next runtime message API.
The prototype for objc_msgSend() is technically variadic - 
`id objc_msgSend(id, SEL, ...)`. 
But all method calls should use a prototype that matches the method, 
not the prototype for objc_msgSend itself().

351762cda2 A few more tweaks to the blocks AST representation:
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

168b80f2c0 Add support for GNU runtime property set / get structure functions.

457a04e3ce Substantially revise how clang computes the visibility of a declaration to
more closely parallel the computation of linkage.  This gets us to a state
much closer to what gcc emits, modulo bugs, which will undoubtedly arise in
abundance.

0ef508d301 Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols
(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration.  'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions.  The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

Fixes <rdar://problem/8380046>.

2dd7d44135 Some more correctness fixes and code-size optimizations for fragile-ABI
ObjC exceptions:
  - don't enter a try for the catch blocks unless there's a finally
  - put the setjmp buffer in the locals set for liveness reasons
  - dump the sync object into an alloca in the locals set for liveness reasons
Some of this can go away if the backend starts to properly calculate liveness
in the presence of setjmp (which would also be a *much* stabler solution).
