[PATCH] D70939: [LoopUtils] Add an utility to delete dead loop nest.

[Whitney Tsang via Phabricator via llvm-commits]

Whitney added a comment.

> what is missing to be correct for nested loops as well?

The only think I can see missing is `LI->erase(L)`, which relink the subloops of L to the parent of L, or change them to top level loops if L has no parent.
