[DRLVM][gc]Concurrent GC phase redesign and scheduler improvement

                 Key: HARMONY-5989
                 URL: https://issues.apache.org/jira/browse/HARMONY-5989
             Project: Harmony

          Components: DRLVM
    Affects Versions: 5.0M7
         Environment: Windows and Linux platform
            Reporter: Simon.Zhou
             Fix For: 5.0M7

Now, Tick is Concurrent GC implementation in Harmony, I improve it in 3 ways:
1, State-based synchronization of mutators and gc collectors.
2, improve the concurrent gc scheduler
3, fix some bugs, one is the bug for array copy, so the vmcore module should be updated also.

it has 18% performance speedup compared with original implementation.
later I will upload a more detail description for this issue.
