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.

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

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.
