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

On the POWER7, adds and logical operations can also be handled
in the load/store pipelines. We'll call these IntSimple.

This adds a full itinerary for IBM's PPC64 A2 embedded core. These
cores form the basis for the CPUs in the new IBM BG/Q supercomputer.
