JDK-8275056 - Virtualize G1CardSet containers over heap region
Description
While looking at JDK-8276540 I noticed that for iterating over Howl-Full card set containers, we iterate the range card-by-card (`do_card`).

It's more efficient to use the range-based visitor method for that (`do_card_range`). Implement this.
