Give preference to type over data constructors for doc comment links at renaming time.
Previously this was done in the backends.
Also, warn when a doc comment refers to something that is in scope but which we
don't have the .haddock file for.
These changes mean we can make DocIdentifier [a] into DocIdentifier a.
