    Description

      In `HeapRegion::oops_on_memregion_iterate_in_unparsable`:

      ```
        if (!bitmap->is_marked(cur)) {
          cur = bitmap->get_next_marked_addr(cur, end);
        }

        while (cur != end) {
          ...
          cur = bitmap->get_next_marked_addr(cur, end);
        }
        ...
      ```

      Both this method and `get_next_marked_addr` are annotated with `inline`. Merge these two call sites into one to reduce #instruction in the assembly.
