--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
The released name comes from tree-ssa:

        {
          if (access_has_children_p (racc)
              && !racc->grp_unscalarized_data)
            {
              if (dump_file)
                {
                  fprintf (dump_file, "Removing load: ");
                  print_gimple_stmt (dump_file, stmt, 0, 0);
                }
              generate_subtree_copies (racc->first_child, lhs,
                                       racc->offset, 0, 0, gsi,
                                       false, false, loc);
              gcc_assert (stmt == gsi_stmt (*gsi));
              unlink_stmt_vdef (stmt);
              gsi_remove (gsi, true);
              release_defs (stmt);
              sra_stats.deleted++;
              return SRA_AM_REMOVED;
            }

The release_defs call releases the SSA_NAME back to the manager.
