	* explow.c (force_reg): Strengthen local "insn" from rtx to
	rtx_insn *.
	(adjust_stack_1): Likewise.
	(allocate_dynamic_stack_space): Likewise.  Strengthen locals
	"final_label", "available_label", "space_available" from rtx to
	rtx_code_label *.
	(probe_stack_range): Likewise for locals "loop_lab", "end_lab".
	(anti_adjust_stack_and_probe): Likewise.
