[PATCH] D30284: [loop-deletion] Improve analysis on calls when deleting a loop.

Well, you could in theory delete a loop which contains an argmemonly call if you can prove the modified memory isn't used outside the loop... but that doesn't come up in practice, as far as I know.  Beyond that, I don't think you can do anything interesting with alias analysis.
