8d816d6cb5 CodeGenModule::GetAddrOfConstantCFString(): 
- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

29cae66bde Add ConvertUTF module from http://www.unicode.org/Public/PROGRAMS/CVTUTF. 
#ifdef'd out the 5 conversion routines that we don't currently need.

Still need a bit more work in GetAddrOfConstantCFString(). Added a FIXME to indicate this.

Expect to remove the FIXME today...

d18136a644 fix the two xfails I added with a previous patch by making ObjC interface 
types get completed when their definition is seen if previously laid out by
the code generator.

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

984fac5f5f most of this is plumbing to get CompileOptions down into 
CodeGenModule.  Once there, add a new NoCommon option to
it and implement -fno-common.

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

75acb0c356 fix a fixme: non-proto struct returning function definitions should be compiled 
to something like:
define void @bar(%struct.foo* noalias sret %agg.result) nounwind {
instead of:
define void @bar(%struct.foo* noalias sret %agg.result, ...) nounwind {

4ff71de880 set function/global names with setName instead of passing the name into the 
ctor function.  This avoids creating a temporary std::string for the name,

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.

99d2835099 Backout r66408, we don't want handling of globals to rely on the 
module symbol table. The root problem inspiring this was fixed in
r66316 (and again in r66506).

4663a3368d Make constant emission for @encode use the common string emission code. 
This is a bit cleaner, and also "fixes" bad code that compares the 
addresses of the string constants.

7aecee998c (LLVM svn up) Generalize RuntimeFunctions to RuntimeGlobals and add 
CodeGenModule::CreateRuntimeVariable.

 - No real functionality change; although we now assert on silly
   things like:
--
int objc_exception_throw;
void f0() { @throw(@"A"); }
--
   instead of accepting it.

f804897ee9 Don't mangle names of local variables. 
- For one thing, this adds unneeded overhead; for another, this
   routine can be used to emit unnamed decls which we shouldn't try to
   mangle.
