================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:2986
+    Value *LHS = ConstantInt::get(
+        Count->getType(), cast<IntegerType>(Count->getType())->getMask());
+    LHS = Builder.CreateSub(LHS, Count);
----------------
There are now three uses or this so perhaps worth breaking out?
