Hello,

We stumbled upon a case where loop-interchange seems to start hanging and consume more and more memory until it cannot do that any longer with this patch:

  opt -passes="loop(loop-interchange,loop-interchange)" bbi-72548.ll -o /dev/null

F24115392: bbi-72548.ll <https://reviews.llvm.org/F24115392>
