This patch introduces a directive set for combined constructs where `teams` is the last leaf. This is used in a couple places to simplify checks, which is NFC, but it also replaces two incorrect uses of `topTeamsSet`. Before, these checks would incorrectly skip combined constructs where `teams` was the last leaf construct when checking for allowed nested constructs inside of a `teams` region. Similarly, it would also incorrectly perform these checks whenever a compound `teams` construct where `teams` was the first leaf construct was found.
