Change the types of arguments and return values for several functions from rtx to...

gcc/ChangeLog:

2014-09-04  Trevor Saunders  <tsaunders@mozilla.com>

	* emit-rtl.c (get_first_nonnote_insn): Return rtx_insn * instead of
	rtx.
	(get_last_nonnote_insn): Likewise.
	(next_nonnote_insn_bb): Take rtx_insn * instead of rtx.
	* resource.c (find_basic_block): Likewise.
	* rtl.h: Adjust.
	* rtlanal.c (keep_with_call_p): Take const rtx_insn * instead of
	const_rtx.
