[PATCH] D115261: [LV] Disable runtime unrolling for vectorized loops.

[Philip Reames via Phabricator via llvm-commits]

@fhahn Can you point to a couple other cases where this is needed for profitability?  I took a look at PR40961, and that really looks more like a problem us figuring out small trip counts and restricting transforms appropriately.  (i.e. the unroller should never be unrolling longer than the total loop trip count)  That's "easily" fixable, and we should do so.
