There is a tracker on bugzilla for it. It's under the
clang-tools-extra umbrella.

No, we just use cfe-dev and cfe-commits.

I'm not certain I've heard of this case coming up before, truth be
told. We write the checks so that they do not run against language
standards that do not support the construct (for instance, no checks
involving lambdas unless you are compiling in c++11 or later), but I
don't believe that will help your scenario out because we don't
otherwise mark the tests as being specific to some language standard
(so you can't filter out the tests other than manually).
