Fix PR19169 [Crash on invalid attempting to specialize a template method as a template variable].
A template declaration of a template name can be null in case we have a dependent name or a set of function templates.
Hence use dyn_cast_or_null instead of dyn_cast. Also improve the diagnostic emitted in this case.
