This patch series adds support for FEAT_CMH,
this includes two patches. The first alters the previous
atomic_store from PCDPHINT to change the hint parameter,
this allows for the new hints to be added from CMH.
The second adds a new set of atomic_fetch intrinsics,
which can be used with the new SHUH hint.
