7200261: G1: Liveness counting inconsistencies during marking verification Summary: The clipping code in the routine that sets the bits for a range of cards, in the liveness accounting verification code was incorrect. It set all the bits in the card bitmap from the given starting index which would lead to spurious marking verification failures. Reviewed-by: brutisso, jwilhelm, jmasa
