Ok. but I want to be very clear what that means.  It means for each AVX
instruction I rip out ALL of the existing SSE support for it.  So when
ADD gets implemented, ADD goes away from X86InstSSE.td.

As things progress, we're almost certainly going to have to refactor or
otherwise change things we've done in the past.  That means extensive
.td changes and some very large commits.

If everyone's ok with this kind of churn on trunk, that's what I'll do.
But SVN branches exist exactly for these kinds of disruptive changes.
We used one for the use-diet so there's precedent.
