cfddabf5a3 Block ivar layout must assume that the 'isa' 
field of the block descriptor is GC'able (scanned)

messages). Radar 8394947.

12d3891a27 It's not safe to use the generic CXXMethodDecl overload of CGT::getFunctionInfo

262e4e2ab5 Fix more i1/i8 pointer madness. Here, an overactive assertion 
complains when the element type of a C++ "delete" expression is
different from what we would expect from the pointer type. When
deleting a bool*, we end up with an i1 on one side (where we compute
the LLVM type from the Clang bool type) and i8 on the other (where we
grab the LLVM type from the LLVM pointer type). I've weakened the
assertion appropriately, and the Boost Parallel Graph Library now
passes its regression tests.

e791a0546c Fix a crash involving pointer-to-data-members of boolean type. We were 
constructing an LLVM PointerType directly from the "bool"'s LLVM type
(i1), which resulted in unfortunate pointer type i1*. The fix is to
build the LLVM PointerType from the corresponding Clang PointerType,
so that we get i8* in the case of a bool. 

John, please review. I also left a FIXME there because we seem to be
dropping "volatile", which would be rather unfortunate.

8ed55a54fd Abstract IR generation of array cookies into the C++ ABI class and 
implement ARM array cookies.  Also fix a few unfortunate bugs:
  - throwing dtors in deletes prevented the allocation from being deleted
  - adding the cookie to the new[] size was not being considered for
    overflow (and, more seriously, was screwing up the earlier checks)
  - deleting an array via a pointer to array of class type was not
    causing any destructors to be run and was passing the unadjusted
    pointer to the deallocator
  - lots of address-space problems, in case anyone wants to support
    free store in a variant address space :)

1b87c9a646 Translate NEON vmull, vmlal, and vmlsl builtins to llvm multiply-add/sub 
with zext/sext operations, instead of to llvm intrinsics.  I have a plan to
avoid the clang builtins for these, but it is going to take a little longer
and I want to get the NEON intrinsics updated before the 2.8 release.

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>.

d426c8eae3 fix rdar://8360877 a really nasty miscompilation in Boost.Xpressive 
caused by my ABI work.  Passing:

struct outer {
  int x;
  struct epsilon_matcher {} e;
  int f;
};

as {i32,i32} isn't safe, because the offset of the second element
needs to be at 8 when it is interpreted as a memory value.
