Warning about this is a good idea. We did something similar when we
(re-)introduced sync_fetch_and_nand, see:
def warn_sync_fetch_and_nand_semantics_change : Warning<
"the semantics of this intrinsic changed with GCC "
"version 4.4 - the newer semantics are provided here">,
InGroup<DiagGroup<"sync-fetch-and-nand-semantics-changed">>;
