RFR: 8274773: [TESTBUG] UnsafeIntrinsicsTest intermittently fails on weak memory model platform

Tue Oct 5 12:35:22 UTC 2021

The test creates new Nodes and publishes them to concurrent readers. This requires at least release and load_consume. A clean fix would be to make `Node.next` volatile. But that would be a sledgehammer. A minimalistic fix for our supported weak memory model platforms is to insert a `storeFence`. What is better?
(See JBS for failure description.)
