Log:
Add element-atomic mem intrinsic canary tests for Efficiency Sanitizer.

Summary:
Add canary tests to verify that ESAN currently does nothing with the element atomic memory intrinsics for memcpy, memmove, and memset.

Placeholder tests that will fail once element atomic @llvm.mem[cpy|move|set] instrinsics have been added to the MemIntrinsic class hierarchy. These will act as a reminder to verify that ESAN handles these intrinsics properly once they have been added to that class hierarchy.
