      In 6379795, HP reported that there were missing memory barriers in the push(), push_slow(), pop_global(), and pop_local_slow() between _age and _bottom fields.

      As part of 688847, store barriers were added to the push() and push_slow() routines but the others mentioned in 6379795 were missed.

      Recently SAP have submitted a patch to the OpenJDK that is a superset of these ordered memory operations.

      This CR is to track this.
