For PR780:
...
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

Be more conservative with our symbolic alias analysis. In particular,
...
don't assume that A[1][0] and A[0][i] can't alias. "i" might be out of
range, or even negative. This fixes a miscompilation of 188.ammp (which
does bad pointer tricks) with the new CFE.
