Sync up with jdk9?

[Aleksey Shipilev]

Hi,

I need to get my hands on reference weakCompareAndSet intrinsics with
Shenandoah. Unfortunately, this means either hacking into
jdk.internal.vm.Unsafe, or going through j.u.c.AtomicReference. I would
prefer the second way, but it requires a pull from jdk9/dev -- the old
j.u.c.AR::weakCAS is calling a strong CAS.

Is there a schedule where the next pull is? I can do this, but I need to
understand what tests are used to smoke test Shenandoah.

Thanks,
