      Description

      This patch is a prerequisite for JDK-8226310.
      Separate root scanner for SH::object_iterate(), enforce strict restriction, so that it can not interfere with concurrent CLDG iteration.

      The specialized root scanner should not clear CLDG's claim mask, and should use _claim_none to walk CLDG.
