mode-switching.c: Use rtx_insn 

gcc/
	* mode-switching.c (struct seginfo): Strengthen field "insn_ptr"
	from rtx to rtx_insn *.
	(new_seginfo): Likewise for param "insn".
	(create_pre_exit): Likewise for locals "last_insn",
	"before_return_copy", "return_copy".
	(optimize_mode_switching): Likewise for locals "insn", "ins_pos",
	"mode_set".
