[drlvm] vm hepler improvement for better performance
----------------------------------------------------

                 Key: HARMONY-5464
                 URL: https://issues.apache.org/jira/browse/HARMONY-5464
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
         Environment: Hope it works everywhere
            Reporter: Maksim Ananjev
         Attachments: xml_derby_fix_osr_enable_commented.patch

The issue deals with "load interface vtable support".  Returning zero address and not generating
NPE if the object is null is safe in terms of preserving program semantics(the exception will
be generatedon the first method invocation) and allows profitable code transformations such
as hoisting vm helper outside the loop body.

The patch also includes osr_path enabling because it depends on this feature.
