[drlvm][em] DRLEM profile collectors code to access method profiles is not thread safe
--------------------------------------------------------------------------------------

                 Key: HARMONY-4000
                 URL: https://issues.apache.org/jira/browse/HARMONY-4000
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Mikhail Fursov


DRLEM profile collectors code to access method profiles is not thread safe.
All 3 profile collectors: entry-backedge, edge and value profilers, do not use locks in getMethodProfile
routine.
However the map that is used to keep method<->profile mapping can be modified from a
separate thread when new profile is created.
