    Description

      Before Shenandoah concurrent weak reference processing, ShenandoahMarkContext only has is_marked() method and it means strongly marked.

      Since implementation of concurrent weak reference processing, ShenandoahMarkContext.is_marked() now means strongly or weakly marked.

      We need to exam and update uses of ShenandoahMarkContext.is_marked(), make sure they are correct.
