The TTI knob can be generalized to something like "hasMemoryIntrinsicsAlwaysAvailable" which would allow decoupling availability of memcpy libcalls from usability of memcpy intrinsics without being overly specific about MemCpyOpt pass.

I'm open about any other suggestions on a better way to get the pass working for NVPTX.
