20adc9dc46 Reapply address space patch after fixing an issue in MemCopyOptimizer. 
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

A update of langref will occur in a subsequent checkin.

0b6cb50738 Factor checked library call optimization into a common helper class and use it 
to unify the almost identical code in CodeGenPrepare and InstCombineCalls.

7fa30b8e5d stpcpy is so similar to strcpy, it doesn't deserve a complete copy of the __strcpy_chk -> strcpy code.

b6174e3605 Move SimplifyLibCalls's LibCall builders to a separate file so they 
can be used in more places.  Add an argument for the TargetData that
most of them need. Update for the getInt8PtrTy() change.  Should be
no functionality change.
