[Nikita Popov via Phabricator via llvm-commits]

> I'd prefer that we IR simplify our way out of this infinite loop instead of looking the other way though. Ie, can we get this in instsimplify using a ConstantRange?

That should be relatively simple to do, we just need to support constant range calculation for min/max flavor selects in computeConstantRange().
