[PATCH] D89800: [ARM][LowOverheadLoops] Don't generate a LOL if lr is redefined after the start

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

When can this happen now? We added lr as a def of t2DoLoopStart so this kind of thing would not be possible, and we would not need to do this expensive / impossible checking so late in the backend, where it is so difficult to get really correct.
