I notice that this refactoring has already been done as part of
8135157: DMB elimination in AArch64 C2 synchronization implementation
Here is an updated version of my webrev against the latest hs-comp which
adapts to that change:
It is basically the last version minus the definitions for enc_class
aarch64_enc_cmpxchg_acq and enc_class aarch64_enc_cmpxchgw_acq (which
have been provided by 8135157).
Would it be ok to push this now?
