The only part of IRA that uses move_costs directly is copy_cost.
It looks like this might be an oversight, since all related costs
already use ira_register_move_cost.
As mentioned in the covering message, the two arrays are usually
the same anyway. The only hitch is that we have:
if (!move
After the preceding patch, only ira_init_register_move_cost uses
the regclass costs directly. This patch moves them to IRA and makes
init_move_cost static to it.
This is just a stepping stone to make the later patches easier to review.

This patch makes the original move_cost calculation match the value

It seems like we really ought to be preserving the contains_reg_of_mode

The previous patch asserted that the first and second sets are now the same,
