Kent-san,

Thank you for review and detailed comments. I've revised the patch. The patch still might be not good enough, but I'd like you to glance over the current implementation.

Following your suggestion, I've added a list of form-associated elements with form attribute. I also added two variables into HTMLFormElement for avoiding performance regression for existing pages. They are indices of m_associatedElements and denotes the range of elements which are children of the form element. These variables are used when form-associated elements which don't have form attribute are inserted. I think it would have less impact on existing pages.

On the other hand, for elements with form attribute, I couldn't come up with efficient ways to handle them. So the current implementation walks through the entire tree of the document to find the right index to be inserted.
