setNeedsBoundariesUpdate is used for updating parent element boundaries in our SVG code. It is currently called from RenderObject::willBeRemovedFromTree() but it's not clear that this is necessary at all (especially for non-SVG renderers).

void RenderObject::setNeedsBoundariesUpdate()
{
    if (RenderObject* renderer = parent())
        renderer->setNeedsBoundariesUpdate();
}

This needs to be investigated further for a potential performance win.
