Added a check for error messages in case of ambiguous specializations and no
matching specialization (in terms of function overloads).
For classes there is no way to cause no matching specialization AFAICT.
Either a primary template will be picked and no error message will be shown or
its requirements will fail and the error message will not mention the
specializations at all.
