Most of these tests used this directive as a way to opt in to a new language feature, and most of those features are already stable for a long time, so no opt-in is needed. Some other tests used the directive to opt out from a language feature, replace those by the `LANGUAGE` directive. One test used the directive to test behavior that actually depended on the API version; use `API_VERSION` directive there instead.
