Hal Finkel 8c33dde666 Split out the PPC instruction class IntSimple from IntGeneral. 
On the POWER7, adds and logical operations can also be handled
in the load/store pipelines. We'll call these IntSimple.

Hal Finkel 9f9f8929ee Add instruction itinerary for the PPC64 A2 core. 
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.

Hal Finkel 59607e63cb Split the LdStGeneral PPC itin. class into LdStLoad and LdStStore. 
Loads and stores can have different pipeline behavior, especially on
embedded chips. This change allows those differences to be expressed.
Except for the 440 scheduler, there are no functionality changes.
On the 440, the latency adjustment is only by one cycle, and so this
probably does not affect much. Nevertheless, it will make a larger
difference in the future and this removes a FIXME from the 440 itin.

Anton Korobeynikov 7d62e33291 Make processor FUs unique for given itinerary. This extends the limit of 32 
FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.

Jim Laskey 74ab9960f2 Added InstrSchedClass to each of the PowerPC Instructions. 
Note that when adding new instructions that you should refer to the table at the
bottom of PPCSchedule.td.
