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.

First baby step towards ppc64 support. This adds a new -march=ppc64 backend
...
that is currently just like ppc32 :)

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 :)

Do the right thing and enable 64 bit regs under the control of a subtarget
...
option. Currently the only way to enable this is to specify the
64bitregs mattr flag. It is never enabled by default on any config yet.

More PPC32 -> PPC changes, as well as merging some classes that were
...
redundant after the change.

1. Use SubtargetFeatures in llc/lli.
...
2. Propagate feature "string" to all targets.
3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

Consolidate the GPOpt stuff to all use the Subtarget, instead of still
...
depending on the command line option. Now the command line option just
sets the subtarget as appropriate. G5 opts will now default to on on
G5-enabled nightly testers among other machines.
