Daniil Suchkov 0e36288318 [LoopPredication] Report changes correctly when attempting loop exit predication 
To make the IR easier to analyze, this pass makes some minor transformations.
After that, even if it doesn't decide to optimize anything, it can't report that
it changed nothing and preserved all the analyses.
