rs6000: Allow mode GPR in cceq_{ior,rev}_compare

Also make it a parmeterized name: @cceq_{ior,rev}_compare_<mode>.

	* config/rs6000/rs6000.md (cceq_ior_compare): Rename to...
	(@cceq_ior_compare_<mode> for GPR): ... this.  Allow GPR instead of
	just SI.
	(cceq_rev_compare): Rename to...
	(@cceq_rev_compare_<mode> for GPR): ... this.  Allow GPR instead of
	just SI.
	(define_split for <bd>tf_<mode>): Add SImode first argument to
	gen_cceq_ior_compare.
