reginfo.c (memory_move_cost): Change rclass argument type form 'enum reg_class' to reg_class_t.

	* reginfo.c (memory_move_cost): Change rclass argument type form
	'enum reg_class' to reg_class_t.
	* reload.h (memory_move_cost): Update prototype.
	* postreload.c reload_cse_simplify_set): Change type dclass var to
	reg_class_t.
	* ira-int.h (ira_allocate_cost_vector, ira_free_cost_vector):
	Update prototype.
	(ira_allocate_and_set_costs): Change aclass argument type form
	'enum reg_class' to reg_class_t.
	* ira-build.c (ira_allocate_cost_vector, ira_free_cost_vector): 
	Change aclass argument type to reg_class_t.
	(update_conflict_hard_reg_costs): Change type aclass and pref vars
	to reg_class_t.
	* gcc/ira.c (setup_class_subset_and_memory_move_costs): Adjust
	memory_move_cost call.

	* config/ia64/ia64.c (ia64_register_move_cost): Remove 'from' and
