[drlvm] [jvmti] Some SingleStep implementation fixes
----------------------------------------------------

                 Key: HARMONY-1507
                 URL: http://issues.apache.org/jira/browse/HARMONY-1507
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
            Reporter: Pavel Rebriy


This patch fixes the following SingleStep bugs:

- Breakpoint was set for a wrong frame for regular bytecodes. The previous frame should be
used only for return type bytecodes
- Bug with uninitialized disassembler field in breakpoints when no other breakpoint is set
in the place where SingleStep breakpoint is going to be created
- Fixed exception RAISE state in breakpoints handler and exception event callback
- Fixed race condition when instrumenting compiled method
- Fixed function get_other_breakpoint_same_location
- Fixed SingleStep location prediction

The patch also adds a lot of tracing useful for debugging SingleStep code.
