Need to improve this part of cpu=samples;

- For each JVMTI frame (likely 6 in the default case)
      - create a frame table element which is a jmethodID and a line number
          But to get the line number it has to convert a byte code
             offset to a line, and must call JVMTI GetLineNumberTable() and search the table.
          best if this happens at the end of processing, before traces are dumped.
Once all the frames are created a unique hprof trace entry is created or found
