================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:1990
+                             BasicBlock *LoopExitBlock) {
+    if (!SCEVCheckBlock)
+      return nullptr;
----------------
Can/Should SCEVCheckCond be used instead? Just to make it symmetric with emitMemRuntimeChecks.
