rs6000: New iterator CCEITHER
This expands to both CC and CCUNS, it's useful for isel for example.
* config/rs6000/rs6000.md (CCEITHER): New define_mode_iterator.
(un): New define_mode_attr.
(isel_signed_<mode>, isel_unsigned_<mode>): Delete, merge into ...
(isel_<un>signed_<GPR:mode>): ... this. New define_insn.
(isel_reversed_signed_<mode>, isel_reversed_unsigned_<mode>): Delete,
merge into ...
(isel_reversed_<un>signed_<GPR:mode>): ... this. New define_insn.
