config/m68k: Use rtx_insn

gcc/
	* config/m68k/m68k-protos.h (output_btst): Strengthen param 4 from
	rtx to rtx_insn *.
	(strict_low_part_peephole_ok): Likewise for param 2 "first_insn".
	(m68k_final_prescan_insn): Likewise for first param.

	* config/m68k/m68k.c (m68k_emit_movem): Likewise for return type.
	(m68k_set_frame_related): Likewise for param "insn".
	(output_btst): Likewise for param "insn".
	(m68k_final_prescan_insn): Likewise.
	(m68k_move_to_reg): Likewise for local "insn".
	(m68k_call_tls_get_addr): Likewise for local "insns".
	(m68k_call_m68k_read_tp): Likewise.
	(strict_low_part_peephole_ok): Likewise for param "first_insn".
	(m68k_output_mi_thunk): Likewise for local "insn".
