[drlvm] [jvmti] Bugs in field watches and stack trace for JIT, jvmtiGetBytecodes and single
step/breakpoints for interpreter
----------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1511
                 URL: http://issues.apache.org/jira/browse/HARMONY-1511
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Gregory Shimansky


This is a patch with several small bugfixes for JVMTI unrelated directly to single step implementation.
The following problems are fixed:

- Field watches callback from JIT should have RAISE_AREA set since it is not an unwindable
code
- Stack trace on JIT should skip top level VM internal java methods because they are not supposed
to be shown to user
- Only on interpreter should VM search for breakpoints in the instrumented method bytecode
because on JIT this bytecode is not touched, the compiled code is changed instead
- When running on interpreter SingleStep event should be sent before Breakpoint event according
to JVMTI spec. ATM there have reverse order
