+    if (Hiding && isa<UsingDecl>(Hiding))
----------------
I'm not sure about this, but is it correct for VisibleDeclsRecord::checkHidden to return the UsingDecl when the UsingShadowDecl is being passed? I'm thinking perhaps the bug is in that function, since it seems like it should just return a nullptr instead if UsingDecl doesn't hide UsingShadowDecl, .
