scope. There are a few contexts in which we assume a name is a template name; if such a context is one where we should perform an unqualified lookup, and lookup finds nothing, we would form a dependent template name even if the name is not dependent. This happens in particular for the lookup of a pseudo-destructor. In passing, rename ActOnDependentTemplateName to just ActOnTemplateName given that we apply it for non-dependent template names too.
