   Intl.Segmenter does not implement UAX #14 which is line breaks which is what we use Intl.v8BreakIterator for. The omission was on purpose, so there isn't something for us to reliably migrate to. We'll have to polyfill like we do with wimp_heavy if Intl.v8BreakIterator's deprecation becomes problematic.

   The new text clusters api may have enough feature to replace the v8BreakIterator.
