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.

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.
