[drlvm] Removing empty files?

[Mark Hindess]

Any reason why we need to keep the following empty files in drlvm:

  vm/vmcore/src/kernel_classes/native/java_lang_VMStart.cpp
    (last changed by geirm r454411 as part of HARMONY-1582)

  vm/jitrino/src/codegenerator/CodeGenIntfc.cpp
  vm/jitrino/src/dynopt/EdgeProfiler.h
  vm/jitrino/src/shared/Exceptions.h
    (last changed by varlax r525110 as part of HARMONY-3511)

Regards,
 Mark.
