Summary: LoopRotate manually updates the DoomTree by iterating over all predecessors of a basic block and computing the Nearest Common Dominator. When a predecessor happens to be unreachable, `DT.findNearestCommonDominator` returns nullptr. This patch teaches LoopRotate to handle this case and fixes [[ https://bugs.llvm.org/show_bug.cgi?id=33701 | PR33701 ]]. In the future, LoopRotate should be taught to use the new incremental API for updating the DomTree.
