Hello,

I bisected a crash back to this commit:

  opt -passes='function(loop-flatten,loop(loop-unroll-and-jam,loop-deletion))' bbi-73307.ll -o /dev/null

crashes with

  opt: ../include/llvm/Analysis/LoopInfo.h:160: const std::vector<LoopT *> &llvm::LoopBase<llvm::BasicBlock, llvm::Loop>::getSubLoops() const [BlockT = llvm::BasicBlock, LoopT = llvm::Loop]: Assertion `!isInvalid() && "Loop not in a valid state!"' failed.
