	* ira.c (init_move_cost): Adjust choice of subclasses to match
	the current ira_init_register_move_cost choice.  Use
	ira_class_subset_p instead of reg_class_subset_p.
	(ira_init_register_move_cost): Assert that move_cost,
	may_move_in_cost and may_move_out_cost already hold the desired
	values for their ira_* equivalents.  For the latter two,
	ignore classes that can't store a register of the given mode.
