re PR sanitizer/79944 (asan: incorrect instrumentation of atomic operations)

PR sanitizer/79944
* asan.c (get_mem_refs_of_builtin_call): For BUILT_IN_ATOMIC* and
BUILT_IN_SYNC*, determine the access type from the size suffix and
always build a MEM_REF with that type.  Handle forgotten
BUILT_IN_SYNC_FETCH_AND_NAND_16 and BUILT_IN_SYNC_NAND_AND_FETCH_16.

* c-c++-common/asan/pr79944.c: New test.
