JDK-8300770 - G1: Allow optional code root memregions
Description
G1 code contains the following piece of code to abort root region scan and wait for its completion twice:

    _cm->root_regions()->abort();
    _cm->root_regions()->wait_until_scan_finished();

Adding a helper removes the code duplication. Further, in the future there is likely need for more work to be done at these places, so factoring out this sequence seems useful.
