when instantiating the declaration of a member template: - Only check if the have a template template argument at a specific position when we already know that we have template arguments at that level; otherwise, we're substituting for a level-reduced template template parameter. - When trying to find an instantiated declaration for a template template parameter, look into the instantiated scope. This was a typo, where we had two checks for TemplateTypeParmDecl, one of which should have been a TemplateTemplateParmDecl. With these changes, tramp3d-v4 passes -fsyntax-only. llvm-svn: 95421
