rs6000: Remove rs6000_emit_sISEL

Browse source 
Instead of calling rs6000_emit_sISEL, call rs6000_emit_int_cmove
directly, in the one place it is used.


	* config/rs6000/rs60000-protos.h (rs6000_emit_sISEL): Delete.
	(rs6000_emit_int_cmove): New declaration.
	* config/rs6000/rs6000.c (rs6000_emit_int_cmove): Delete declaration.
	(rs6000_emit_sISEL): Delete.
	(rs6000_emit_int_cmove): Make non-static.
	* config/rs6000/rs6000.md (cstore<mode>4): Use rs6000_emit_int_cmove
	instead of rs6000_emit_sISEL.
