It isn't clear to me what you are suggesting here.  You want to convert
an addl to a movl?  How can that work, and what benefit do we get from
it?  Or maybe you meant this the other way around?

Anyways, it is clear that you want a new kind of relaxation that may
conflict with the existing ones, but ...

So you don't actually know if the 3rd pass is necessary.  Perhaps you
should resubmit the patch when you do know for sure whether it is
necessary.
