[String] Only bridge tagged NSStrings to small string form.
5f1ba83 
Non-tagged NSStrings carry identity separate from their
value. Continue to bridge them lazily, even if they could fit in small
form, to respect this and avoid potential information loss.

Temporarily disable invariant that all natives strings that could be
small, are.
