Split several PPC instruction classes.
Slight reorganisation of PPC instruction classes for scheduling. No
functionality change for existing subtargets.
- Clearly separate load/store-with-update instructions from regular loads and stores.
- Split IntRotateD -> IntRotateD and IntRotateDI
- Split out fsub and fadd from FPGeneral -> FPAddSub
- Update existing itineraries
Patch by Tobias von Koch.
