[PATCH] D146376: Update static_assert message for redundant cases

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added a comment.

The changes need a release note and please do add more text to the `expected-error` comments so we can see what the diagnostic actually produces (instead of just `{{failed}}`).
