2016-11-14  Trevor Saunders  <tbsaunde+gcc@tbsaunde.org>

	* config/aarch64/aarch64.c (aarch64_emit_unlikely_jump): split
	up variables to make some rtx_insn *.
	* config/alpha/alpha.c (emit_unlikely_jump): Likewise.
	* config/arc/arc.c: Likewise.
	* config/arm/arm.c: Likewise.
	* config/mn10300/mn10300.c (mn10300_legitimize_pic_address):
	Likewise.
	* config/rs6000/rs6000.c (rs6000_expand_split_stack_prologue):
	Likewise.
	* config/spu/spu.c (spu_emit_branch_hint): Likewise.
