Jonas Paulsson 435ba72afd [SystemZ] Simplify handling of AtomicRMW instructions. (#74789) ...

Let the AtomicExpand pass do more of the job of expanding
AtomicRMWInst:s in order to simplify the handling in the backend.

The only cases that the backend needs to handle itself are those of
subword size (8/16 bits) and those directly corresponding to a target
instruction.
