ppc64asm: fix plan9 style decoding issues This reworks the decoding of CR bit fields to correctly decode the fcmp/cmp/setbc families of instructions. Comparison instructions always produce a result in a CR field, thus it should be listed last if not implied to be CR0. Furthermore, remove the context sensitive decoding of CR field and CR bit type arguments from plan9Arg. These edge cases are better handled during the per-instruction combining of decoded arguments. This allows setbc like instructions to decode correctly without special handling.
