7095236: G1: _markedRegions never contains NULL regions
Summary: Removed the code for skipping over NULL regions in _markedRegions, replacing it with an assertion that a NULL region is never encountered; removed dead methods, remove() and remove_region(), and inlined a simplified addRegion() directly into fillCache().

1228 * IOExceptions, which typically indicate fatal errors. | |

1234 * that the only reasonable operation on an interrupted stream is to | |
