New description:

 When a user object is saved using `edit_user()` (i.e, after editing the
 user settings) WP will discard (and replace with `en_US`) any submitted
 value for the new user `locale` meta if it is not part of the array
 returned by `get_available_languages()`

 `get_available_languages()` works by scanning the language folder for
 `.mo` files. In some use cases, language files might not exist for a
 locale, named in a different way, or maybe stored elsewhere.
 `get_available_languages()` results should be filtrable.

 FWIW: we need this filter (or an alternate solution) to merge the new user
 locale setting and locale switching to WP.com.
