[PATCH] D72420: [LoopRotate] Add support for rotating loops with switch exit

I'm not sure. It might make more sense to make SimplifyCFG be less aggressive about forming switches in this case. Pretty sure that converting `if (a == C || B == C2)` into a switch is pretty much a strict regression in optimization power, because a lot more passes support branches than switches.
