      Description

      Currently in our various oop closures used during gc and during concurrent operation we use different methods to determine out-of-region references, and during GC we sometimes enqueue references and sometimes add remembered set entries directly.

      Enqueuing references also determines whether the from-region is young for every reference - actually that can be determined per object already, and is often already available.
