  original commit message:
  Note: This is currently only used by yield*, we still need to support it in
  other places (such as for-of loops).  It can be used manually of course.

  (This CL does not touch the full-codegen implementation of yield* because that
  code is already dead.  The yield* desugaring already supports return and doesn't
  need to be touched.)
