An explicit template specialization can cause the implicit template
specialization of a type which inherits the attributes. In such a case, we
would end up with a delayed template specialization for a dll exported type
which we would fail to reference. This would trigger an assertion.
We now propagate the dll storage attributes through the inheritance
chain. Only after having done so do we reference the delayed template
specializations. This allows any implicit specializations which inherit dll
storage to also be referenced.
