        (WebCore::wrapperOwner):
        (WebCore::wrapperContext):
        (WebCore::toJS): Use the opaque roots system for DOMImplementation. Also,
        DOMImplementation does not need to keep its document wrapper alive, since
        there's no DOM API for getting a DOMImplementation's document.

        (WebCore::DOMImplementation::deref):
        (WebCore::DOMImplementation::document): Fixed the DOMImplementation
        ownership model to match other satellite objects in the DOM. This was
        necessary to fix some crashes due to incorrect reference counting.

        * dom/DOMImplementation.idl:

        * fast/dom/dataset-gc-expected.txt:
        * fast/dom/script-tests/dataset-gc.js: Changed this test not to be
        specific to __proto__. We have a general bug in the DOM that assignment
        to __proto__ does not persist after garbage collection. While we should
        fix that bug, we don't want existing tests to tickle it, because it makes
        them flaky.
