================
Comment at: clang/lib/AST/TypePrinter.cpp:1020
 
   switch (T->getUTTKind()) {
     case UnaryTransformType::EnumUnderlyingType:
----------------
Couldn't we use `TextNodeDumper::VisitUnaryTransformType` to dump the string and then simplify it to a single case.

Given the possibility that maybe some day one might add the `add_foo` builtins


================
Comment at: clang/lib/Parse/ParseDeclCXX.cpp:1110
+  if (T.expectAndConsume(diag::err_expected_lparen_after,
+                         "reference manipulation builtin",
+                         tok::r_paren)) return;
----------------
