[PATCH] D115356: [LV] Remove what seems like stale code in collectElementTypesForWidening.

================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:5993
 
-      // Ignore loaded pointer types and stored pointer types that are not
-      // vectorizable.
-      //
-      // FIXME: The check here attempts to predict whether a load or store will
-      //        be vectorized. We only know this for certain after a VF has
-      //        been selected. Here, we assume that if an access can be
-      //        vectorized, it will be. We should also look at extending this
-      //        optimization to non-pointer types.
-      //
-      if (T->isPointerTy() && !isConsecutiveLoadOrStore(&I) &&
-          !isAccessInterleaved(&I) && !isLegalGatherOrScatter(&I))
+      if (!T->isSized())
         continue;
----------------
Can this be an assertion? The load/store type can't be unsized, and I assume a reduction type can't be unsized either?
