WebCore:

Reviewed by Sam and Oliver.

• fixed  http://bugs.webkit.org/show_bug.cgi?id=16289
• fixed Acid3 tests 26 and 27 (not exactly the same issue but related)

• bindings/js/JSNodeCustom.cpp: (WebCore::JSNode::mark): When marking a node that's in-document, mark the owner document if it hasn't been already. This means holding on to a single node from an unreferenced document now keeps the whole document alive.

We are now at 90/100 on Acid3.

LayoutTests:

Reviewed by Sam and Oliver.

• test for  http://bugs.webkit.org/show_bug.cgi?id=16289

• fast/dom/gc-11-expected.txt: Added. Test case from bug 16289.
• fast/dom/gc-11.html: Added.
• fast/dom/gc-acid3.html: Added. DOM garbage collection part of Acid3.
• fast/dom/gc-acid3-expected.txt: Added.
• fast/dom/gc-6-expected.txt: Updated results. The old assumptions of this test were in conflict with the requirements of Acid3.
