We can (and probably should) make them available in `flang-new` then. As for `-fdebug-dump-provenance`,  it sounds like it should remain in `flang-new -fc1`.

We can have experimental flags in both drivers. I'm not suggesting any strict rules here. But, for every option that we add, we need to make a decision whether it's:

1. only available in `flang-new`
2. only available in `flang-new -fc1`
3. available in both `flang-new` and `flang-new -fc1`
