rs6000: Allow any CC mode in movcc

Browse source 
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.
