Reviewed by Ryosuke Niwa.

Use a WeakPtr for InlineStylePropertyMap::m_element so the the Element
destructor doesn't have to reset this pointer.

Also, stop calling Document::removeElementWithLangAttrMatchingDocumentElement()
since Document::m_elementsWithLangAttrMatchingDocumentElement is a WeakHashSet.
