Clean up useless initialization for IRA if using LRA. 

gcc/
	* ira.c (ira): Don't initialize ira_spilled_reg_stack_slots and
	ira_spilled_reg_stack_slots_num if using lra.
	(do_reload): Remove release ira_spilled_reg_stack_slots part.
	* ira-color.c (ira_sort_regnos_for_alter_reg): Add assertion to
	make sure not using lra.
	(ira_reuse_stack_slot): Likewise.
	(ira_mark_new_stack_slot): Likewise.
