[PATCH] D40874: [LV][LoopInfo] Add irreducible CFG detection for outer loops

Yes, this is NFC. Since this is kind of a refactoring, there are already tests for the 'containsIrreducibleCFG' utility function in ShrinkWarp and LV passes.
I'm introducing more tests targeting outer loops in the subsequent patch (https://reviews.llvm.org/D42447), which starts to enable the outer loop functionality in LV.
At this point, LV skips all the outer loops so I cannot do any testing in that regard.
