…e implementation This fixes an issue where overriding `clang::ConstTemplateArgumentVisitor::VisitTemplateArgument` in an implementation visitor class did not have the desired effect: the overload was not invoked when one of the visitor methods (e.g. `VisitDeclarationArgument`) is not implemented, instead it dispatched to `clang::ConstTemplateArgumentVisitor::VisitTemplateArgument` itself and always returned a default-initialized result. This makes `TemplateArgumentVisitor` and `ConstTemplateArgumentVisitor` follow the implicit convention that is followed elsewhere in Clang AST, in `RecursiveASTVisitor` and `TypeVisitor`. (cherry picked from commit d4525b0)
