[IRBuilder] Add APIs for creating calls to atomic memmove and memset intrinsics. (NFC)

Browse Source 
Summary:
Creating the IRBuilder methods:
 CreateElementUnorderedAtomicMemSet
 CreateElementUnorderedAtomicMemMove

These mirror the methods that create calls to the regular (non-atomic) memmove and
memset intrinsics.
