m32c.c (classes_intersect): Remove.

	* config/m32c/m32c.c (classes_intersect): Remove.
	(m32c_preferred_reload_class, m32c_secondary_reload_class): Use
	reg_classes_intersect_p instead of classes_intersect.
	(class_can_hold_mode): Change arguments type from enum reg_class to
	reg_class_t.  Use reg_class_contents instead of class_contents.
	(m32c_register_move_cost): Make static. Change arguments type from
	enum reg_class to reg_class_t. Use reg_classes_intersect_p instead of
	classes_intersect. Use reg_class_contents instead of class_contents.
	(m32c_memory_move_cost): Make static. Change arguments type from
	enum reg_class to reg_class_t.
	(TARGET_REGISTER_MOVE_COST, TARGET_MEMORY_MOVE_COST): Define.
	* config/m32c/m32c.h (REGISTER_MOVE_COST, MEMORY_MOVE_COST): Remove.
	* config/m32c/m32c-protos.h (m32c_register_move_cost,
	m32c_memory_move_cost): Remove.
