> Write barrier support for jet in drlvm.
> Original jet in drlvm does not support write barrier, so a GC which needs write barrier
can not be integrated into drlvm which use jet.
> The patch adds write barrier in jet code.
> Completness of the write barriers was checked using per-slot comparison in stop-the-world
GC.
