Teresa Johnson 3be58ceecd Add zero-length check to memcpy/memset load store loop expansion ...

Summary:
I was testing using this expansion logic in other cases besides
NVPTX, and found some runtime failures due to the lack of a check
for a zero length memcpy/memset before the loop. There is already
such a check in the memmove expansion code though.
