[drlvm] Partial SingleStep implementation for drlvm

                 Key: HARMONY-1455
                 URL: http://issues.apache.org/jira/browse/HARMONY-1455
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Gregory Shimansky

The implementation of SingleStep even is based on Breakpoints support in JVMTI and HARMONY-1422
next bytecode predictor.

This actual patch contains initial SingleStep support added to the breakpoints handler of
JVMTI. It also enableds/disables SingleStepping when SingleStepping is turng on/off. It should
start SingleStepping exception handler and when running a new Java method from VM native code.
When execution control is transferred to Java, it should start SingleStepping it from the
transfer location.

TODO is to check that this implementation actually works :) I'll file other JIRAs if I find
bugs in it.
