The changes in JDK-8253064 are primarily from [~eosterlund]

Hmm! I seem to recall we chopped off some alignment previously used to ensure certain fields in the monitor were on different cache lines. It was motivated by being simpler and I couldn’t see it made a difference in workloads I tried. But perhaps this workload is the one workload where this might matter.
