Locale.toLanguageTag will transform the obsolete (and
deprecated) language codes "in", "ji" and "iw" to
"id", "yi" and "he" respectively.
All versions of android prior to "L" used the deprecated
language tags, so we will need to support them for backwards
compatibility.

(cherry-picked from commit 21fc8ba39c)
(also contains a partial cherry-pick of 857ba4af because
including it is the easiest way to avoid conflicts.)
