Ok, good.  The rather old opt ref manual that I had didn't cover these.
The one I downloaded this afternoon does.  And it seems that we would
need new costs fields to properly model the more recent intel cpus.

I don't suppose I could convince you or your cohorts to add some new
fields to the cost struct to handle vector integer operations?  Prolly
only need logical and mult?
