Rename some subtarget features. A CPU now can *have* 64-bit instructions,
...
can in 32-bit mode we can choose to optionally *use* 64-bit registers.

Several big changes:
...
1. Use flags on the instructions in the .td file to indicate the PPC970 unit
type instead of a table in the .cpp file. Much cleaner.
2. Change the hazard recognizer to build d-groups according to the actual
algorithm used, not my flawed understanding of it.
3. Model "must be in the first slot" and "must be the only instr in a group"
accurately.

Add a subtarget feature for the stfiwx instruction. I know the G5 has it,
...
but I don't know what other PPC impls do. If someone could update the proc
table, I would appreciate it :)

to group appropriately and provide cues to maintainers that the lists don't
