[PATCH] D119965: [LICM][PhaseOrder] Don't speculate in LICM until after running loop rotate

lebedev.ri added a comment.

If this is really as simple as all the incoming values being identical instructions with identical arguments, then it seems like a simple extension of the `InstCombinerImpl::foldPHIArgOpIntoPHI()`
