make next/prev nonnote_nondebug_insn take rtx_insn *

gcc/ChangeLog:

2016-09-22  Trevor Saunders  <tbsaunde+gcc@tbsaunde.org>

	* config/cris/cris.c (cris_asm_output_case_end): Change argument
	type to rtx_insn *.
	* emit-rtl.c (next_nonnote_nondebug_insn): Likewise.
	(prev_nonnote_nondebug_insn): Likewise.
	* config/cris/cris-protos.h: Adjust prototype.
	* rtl.h: Likewise.
	* jump.c (rtx_renumbered_equal_p): Adjust.
