	* explow.c (optimize_save_area_alloca): Do not accept parameters.
	* passes.c (rest_of_handle_final): Handle symout.
	(rest_of_handle_new_regalloc, rest_of_handle_old_regalloc):
	Push timevar here.
	(rest_of_handle_sched): Break out SMS.  Remove ifs for
	flag_schedule_insns and flag_modulo_sched.
	(rest_of_handle_addressof, rest_of_handle_cse2): Garbage
	collect at the end.
	(rest_of_handle_gcse2): Put under timevar TV_RELOAD_CSE_REGS.
