Anna Thomas 834c44bc32 [Atomics][LoopIdiom] Recognize unordered atomic memcpy
Summary:
Expanding the loop idiom test for memcpy to also recognize unordered atomic memcpy.
The only difference for recognizing
an unordered atomic memcpy and instead of a normal memcpy is
that the loads and/or stores involved are unordered atomic operations.
