Wait a sec: what does this mean?

"Phi-like recipe with different number of operands and predecessors."

It's a failure?

```cpp
    if (auto *PhiIRI = dyn_cast<VPIRPhi>(&*RecipeI)) {
      if (PhiIRI->getNumOperands() != VPBB->getNumPredecessors()) {
        errs() << "Phi-like recipe with different number of operands and "
                  "predecessors.\n";
        // TODO: Print broken recipe. At the moment printing an ill-formed
        // phi-like recipe may crash.
        return false;
      }
    }
```

Will revert the patch instead.
