        Description

        In an effort to scan more root sets concurrently, we need to support IN_NATIVE oops not being fixed up in safepoints. Both the ZBarrierSetAssembler, ZBarrierSetC1 and ZBarrierSetC2 already have IN_NATIVE load barriers on for all strong oops. However, ZBarrierSet does not yet enable it. I propose to enable it so we can scan more things concurrently.
