Comment at: lib/CodeGen/SelectionDAG/TargetLowering.cpp:3007-3008
     // constant being emitted.
+    assert(!N0.getValueType().isInteger() &&
+           "Integer types should be handled by FoldSetCC");

FoldSetCC is called at the start of this function now so I think we should be safe - but I'm happy to update the if to:
```
if (N0 == N1 && !N0.getValueType().isInteger()) {
```
