In this patch `getFragmentsForTemplateArguments`, which is being called here, is changed to accept `ArrayRef<TemplateArgumentLoc>` (which is what the changed line returns) instead of `ArrayRef<NamedDecl *>` because of the nasty loop that was deleted in `DeclarationFragments.cpp:962`. A `TemplateArgumentLoc` gives us the name of the specialization's type argument directly, instead of comparing with the declaration's template parameters.
