Subject: [PATCH] Remove Xcode prerelease warnings.

At this point we probably do want to know about issues that crop up in
betas so we can fix them before the new version of Xcode is released.
Additionally, this doesn't really work well any more with our new
tag-based workflow as it means we need to cut a new tag immediately
after a new Xcode is released.
