Yep r360704 solves this issue, by weakening the assertion to allow top-level
loops to remain in LoopToAliasSetMap. 

We subsequently clear the map during finalization. There is not much else we
can do with the current structure, as the removed loop object is already
invalid when we call back to LICM to clean up the map.

I also can't repro using the original source in the first comment.

Let's close this.
