* function.c (try_fit_stack_local, add_frame_space): New static

	functions.
	(assign_stack_local_1): Use them.  Look for opportunities to use
	space previously wasted on alignment.
	* function.h (struct frame_space): New.
	(struct rtl_data): Add FRAME_SPACE_LIST member.
	* reload1.c (something_was_spilled): New static variable.
	(alter_reg): Set it.
	(reload): Test it in addition to testing if the frame size changed.
