f77e292a0f Fix a subtle bug where the cleanup scope entries had a dangling block reference 
- <rdar://problem/6732143> Crash when generating @synchronize for
   zero-cost exception

 - Thanks to Anders for helping track down the problem.

08b216abf1 Add Target hooks for IRgen of [cf]string literals. 
- Notably, set section on cfstring literal string data (for now, this
   is done everywhere because it matches what we were already doing
   for the CFString data itself)

 - <rdar://problem/6599098> [irgen] linker requires objc string data
   to go into cstring

8b7b1b1aee Change compound assignment operators to keep track of both the promoted 
LHS type and the computation result type; this encodes information into 
the AST which is otherwise non-obvious.  Fix Sema to always come up with the 
right answer for both of these types.  Fix IRGen and the analyzer to 
account for these changes.  This fixes PR2601.  The approach is inspired 
by PR2601 comment 2.

Note that this changes real *= complex in CodeGen from a silent 
miscompilation to an explicit error.

I'm not really sure that the analyzer changes are correct, or how to 
test them... someone more familiar with the analyzer should check those 
changes.

e64911a4ae switch getBuiltinLibFunction to use the new GetOrCreateLLVMFunction 
functionality, fixing a crash on the attached testcase.  Eliminate the
BuiltinFunctions cache, as it can contain dangling pointers.  This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

6574906818 fix several problems with asm renaming, by pulling it into the mangling code: 
1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

for such things. Per PR3618, verified that we're getting the right

8ce48d8c10 x86_32 ABI: Don't try and expand structures with bitfields. 
- This is an ABI incompatiblity, but this is not likely to be a huge
   deal in practice. For now we at least generate self consistent code
   instead of crashing.

operands).
