[drlvm][performance] ObjectStreamClass lookup improvement

                 Key: HARMONY-5633
                 URL: https://issues.apache.org/jira/browse/HARMONY-5633
             Project: Harmony
          Issue Type: Improvement
            Reporter: Aleksey Shipilev

For now, ObjectStreamClass (OSC) is created on-the-fly during serialization/deserialization
and stored in static cache.
Performance problems arose when several threads doing the lookups, hitting on synchronized
cache. Moreover, the cache is built around WeakHashMap to ensure GC of OSCs. This issue is
the source of scalability problems for multi-threaded serialization benchmarks.
