    Description

      Current AutoBoxing elimination is only works for boxing code (inlined valueOf() methods) when boxed value load is near boxing code.
      Add experimental code to eliminate all non-escaping boxing objects (including new instances) by aggressively propagating loads from such objects through graph.
