d272cca527 Internal variables could mistakenly have "hidden" visibility when
their emission was deferred.

e80bd1897c x86-32 Darwin ABI: Handle small structures correctly.
- Small structures are returned in a register if: 
    1. They fit nicely in a  register.
    2. All fields fit nicely in a register.
   (more or less)

 - We now pass the first 5000 ABITests if unions are disabled.

 - Also, vectors inside "single element structs" require special

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)

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

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.
