7035144: G1: nightly failure: Non-dirty cards in region that should be dirty (failures still exist...) Summary: We should only undirty cards after we decide that they are not on a young region, not before. The fix also includes improvements to the verify_dirty_region() method which print out which cards were not found dirty. Reviewed-by: johnc, brutisso
