ira-int.h (target_ira_int): Add x_max_struct_costs_size...

gcc/
	* ira-int.h (target_ira_int): Add x_max_struct_costs_size, x_init_cost,
	x_temp_costs, x_op_costs, x_this_op_costs and x_cost_classes.
	* ira-costs.c (max_struct_costs_size, init_cost, temp_costs, op_costs)
	(this_op_costs, costs_classes): Redefine as macros.
	(record_reg_classes): Don't take op_costs as a parameter.
	(record_operand_costs): Likewise.  Update calls to record_reg_classes.
	(scan_one_insn): Update call to record_operand_costs.
