LGTM - with one minor



================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:48905
+          V.hasOneUse() && V.getOperand(0).hasOneUse() &&
+          isNullConstant(V.getOperand(1)))
+        return V.getOperand(0);
----------------
I guess you can test the isNullConstant first ?
