Without your patch, if `ICB->getCalledFunction() != nullptr`, then you would do:

```
        if (NewCallee)
          if (!NewCallee->isDeclaration())
            Calls->push({ICB, NewHistoryID});
```

With your patch but without the contexual profile, that behavior seems to be lost.  Is that intended?
