internal-fn.c: Use rtx_insn and rtx_code_label

gcc/
	* internal-fn.c (ubsan_expand_si_overflow_addsub_check):
	Strengthen locals "done_label", "do_error" from rtx to
	rtx_code_label *.
	(ubsan_expand_si_overflow_addsub_check): Strengthen local "last"
	from rtx to rtx_insn *.  Strengthen local "sub_check from rtx to
	rtx_code_label *.
	(ubsan_expand_si_overflow_neg_check): Likewise for locals
	"done_label", "do_error" to rtx_code_label * and local  "last" to
	rtx_insn *.
	(ubsan_expand_si_overflow_mul_check): Likewise for locals
	"done_label", "do_error", "large_op0", "small_op0_large_op1",
	"one_small_one_large", "both_ops_large", "after_hipart_neg",
	"after_lopart_neg", "do_overflow", "hipart_different"  to
	rtx_code_label * and local  "last" to rtx_insn *.
