If `TypeRefVisitor<DemanglingForTypeRef, Demangle,NodePointer>::visit` returns `nullptr`, we should pass it through. The callers of `TypeRef::getDemangling()` are already prepared to cope with `nullptr` returns, so this should be fine and avoids hitting an assertion failure in that case. rdar://120941628
