LGTM aside from a minor nit, thank you!



================
Comment at: clang/lib/Sema/SemaDeclCXX.cpp:11681
+  if (isa<UnresolvedUsingIfExistsDecl>(Target) !=
+      (NonTag && isa<UnresolvedUsingIfExistsDecl>(NonTag))) {
+    if (!NonTag && !Tag)
----------------
You can use `isa_and_nonnull<>()` instead of testing for null yourself.
