Anna Thomas 5f5dc1a4be [BasicBlockUtils] Check for unreachable preds before updating LI in UpdateAnalysisInformation ... Summary: We are incorrectly updating the LI when loop-simplify generates dedicated exit blocks for a loop. The issue is that there's an implicit assumption that the Preds passed into UpdateAnalysisInformation are reachable. However, this is not true and breaks LI by incorrectly updating the header of a loop. One such case is when we generate dedicated exits when the exit block is a landing pad (through SplitLandingPadPredecessors). There maybe other cases as well, since we do not guarantee that Preds passed in are reachable basic blocks. The added test case shows how loop-simplify breaks LI for the outer loop (and DT in turn) after we try to generate the LoopSimplifyForm.
