Revised proposed patch

Here's a revised patch. It has the following differences:

- it now patches cleanly against ToT.
- I cleaned up some style problems, like a few ASSERT usages that I somehow
- I added test cases for the direct write bugs. The array one wouldn't actually
fail for any version of the code, because AssignBracketNode doesn't do direct

I hope I didn't miss anything. There is only one bad thing of which I am aware.
When I run the entirety of the layout tests or just fast/dom,
fast/dom/constructors-overriding.html will sometimes crash, but I can't get it
to crash on its own. The crash is in ActivationImp::mark(), which is modified
by this patch. It doesn't seem to crash without the patch (I didn't try on my
machine, I am just going by the build bot and Mark).
