I think the main question with this patch is whether this is a good idea.  Can you explain how you plan to use these APIs in the autofill flow?  Will you need to create mutation observers for all (or a large fraction) of web pages?  My understanding is that the presence of mutation observers slows down DOM operations.

> +#include "platform/WebPrivatePtr.h"
> +#include "platform/WebVector.h"

We've changed the style for these sorts of includes.
