config/rs6000: Use rtx_insn

gcc/
	* config/rs6000/rs6000-protos.h (output_cbranch): Strengthen param
	4 from rtx to rtx_insn *.
	(rs6000_final_prescan_insn): Likewise for first param.
	* config/rs6000/rs6000.c (rs6000_emit_set_const): Likewise for
	local "insn".
	(rs6000_get_some_local_dynamic_name): Likewise.
	(output_cbranch): Likewise for param "insn".
	(spe_func_has_64bit_regs_p): Likewise for locals "insns", "insn".
	(rs6000_function_ok_for_sibcall): Likewise for locals "top", "insn".
	(rs6000_emit_allocate_stack): Likewise for local "insn".
	(load_cr_save): Likewise.
	(restore_saved_cr): Likewise.
	(restore_saved_lr): Likewise.
	(emit_cfa_restores): Likewise.
	(rs6000_output_function_epilogue): Likewise for locals "insn" and
	"deleted_debug_label".
