Comment at: llvm/lib/Transforms/InstCombine/InstCombineShifts.cpp:216-220
+      Type *ExtendedScalarTy = Type::getIntNTy(Ty->getContext(), 2 * BitWidth);
+      Type *ExtendedTy =
+          Ty->isVectorTy()
+              ? VectorType::get(ExtendedScalarTy, Ty->getVectorNumElements())
+              : ExtendedScalarTy;
----------------
This is duplicated, will later hoist into `Type` itself.
