David Majnemer 4c82daea60 LoopRotate: Don't walk the uses of a Constant ...

LoopRotate wanted to avoid live range interference by looking at the
uses of a Value in the loop latch and seeing if any lied outside of the
loop.  We would wrongly perform this operation on Constants.

This fixes PR22337.
