llvm-6502/lib/Transforms/InstCombine/InstCombineLoadStoreAlloca.cpp
Chandler Carruth ec68f552f2 Port the global copy optimization from the SROA pass to InstCombine. 
This optimization is really just replacing allocas wholesale with
globals, there is no scalarization.

The underlying motivation for this patch is to simplify the SROA pass
and focus it on splitting and promoting allocas.
