https://bugs.webkit.org/show_bug.cgi?id=120358 Reviewed by Andreas Kling. * dom/ContainerNode.h: Delete isContainerNode() so it can't be called if there is static knowledge that the object is a ContainerNode. * dom/DescendantIterator.h: (WebCore::::DescendantIterator): Make DescendantIterator use Node* as root instead of ContainerNode*. It is only used for equality comparison. (WebCore::::begin): Remove branch. Rely on ElementTraversal specialization for ContainerNodes. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@154682 268f45cc-cd09-0410-ab3c-d52691b4dbfc
