rs6000: Allow any CC mode in movcc
Sometimes combine wants to do a move in CCFPmode, but we don't currently
handle moves in any CC mode other than CCmode. Fix that oversight.
* config/rs6000/rs6000.md (CC_any): New mode iterator.
(*movcc_internal1): Rename to...
(*movcc_<mode> for CC_any): ... this. Support moves of all CC modes.
