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.

- Store bindings using a MemRegion -> SVal binding instead of VarDecl -> SVal
  binding. This mirrors some of the idea of RegionStore, but is far simpler and
  not nearly as functional.  This leads to some code simplification and
  some potential for some minor precision hacks.
  
Along the way...
- constify the use of MemRegion* in a few places
- add operator<<(llvm::raw_ostream, const MemRegion*)

Stack dump:
0.	Program arguments: clang t.c -emit-llvm 
1.	<eof> parser at end of file
2.	t.c:1:5: LLVM IR generation of declaration 'a'

Abort

Introduce a new PrettyStackTraceDecl.
Use it to add the top level LLVM IR generation stuff in 
Backend.cpp to stack traces.  We now get crashes like:

Stack dump:
0.	Program arguments: clang t.c -emit-llvm 
1.	<eof> parser at end of file
2.	t.c:1:5: LLVM IR generation of declaration 'a'
Abort

for IR generation crashes.
