      Description

      - when an arraycopy is turned into loads/stores and the field or
        element being copied is a reference. In that case, barriers may have
        to be applied.

      - when a clone is expanded into a stub call. In that case a
        postbarrier may be required. That one is only required when a
        reference field or element may be encountered. That's where the
        ciInstanceKlass changes come in.
