      Summary

      Change experimental flag "UseSystemMemoryBarrier" to regular product flag.

      Problem

      The enhancement JDK-8292591 has introduced the experimental feature "UseSystemMemoryBarrier" which improves performance in some scenarios. It is currently not supported in production, so, customers can't benefit from it.

      Solution

      Make the flag a regular product flag.

      Specification

        product(bool, UseSystemMemoryBarrier, false,                              \
       "Try to enable system memory barrier if supported by OS")         \
