ISA v3.1 introduces new sync types for store ordering.

  stncisync
  stcisync
  stsync

Add ppc-opcode defines for these. This changes PPC_RAW_SYNC to take
L,SC parameters and adds a PPC_RAW_HWSYNC for callers that want the
plain old sync (aka hwsync).

I checked these against the ISA and they seem correct.

Did you consider changing LWSYNC to be defined in terms of your new
PPC_RAW_SYNC?

Oh I haven't but it would be consistent to change that wouldn't it?
