[DRLVM](JIRA-1898) write barrier for C/C++ based GCs in Jitrino.OPT

Hi, the patch attached in JIRA 1898 is an implementation of write barrier
for C/C++ based GCs in Jitrino.OPT. . It would be great if some commiter can
help to review and commit it.

http://issues.apache.org/jira/browse/HARMONY-1898

Repeat the desciption :
"Attached patch is an implementation of write barrier for C/C++ based GCs in
Jitrino.OPT. The patch lets OPT to call "gc_requires_barriers()" of GC to
determine if it needs to insert the write barrier code into the jitted code,
so it doesn't impact current DRLVM/GC at all. It calls
gc_heap_slot_write_ref( ) of GC module.

To Apply this patch, please enter vm/ directory and patch it. You can pass
'-Xem:opt' to EM to use the OPT-only mode. In any other modes, you should be
sure to open the JET write barrier for C/C++ based GCs .

This patch is based on revision 465123.

Please review this patch and see if it's ready for commission. Thanks. We
hope it can be committed to Harmony soon. "

Thanks and Regards!
