      Description

      In JDK-8197928 we introduced a filter to not enqueue deferred cards for regions we do not track the remembered sets for during gc based on whether the target region. This has been a very simple and presumably slow filter.

      Do some more improvements / tests to see whether this can and should be improved.

      One suggestion is to use a per-region array with flags indicating whether this region has a remembered set.
