D is never null here, this if seems to be redundant.
Also, should we `assert` that `D != nullptr` when we deserialize
`PreferredName`?
If we start deferring more attributes at some point, an assertion like this
might not hold up, but it gives a good sanity check for preferred name
specifically, because it should always be attached to some declaration.
