Reviewed by Alan Baradlay.

Make it possible to mark a render subtree for rebuild without needing to recompute the style.

* Source/WebCore/dom/Element.cpp:
(WebCore::Element::invalidateStyleAndRenderersForSubtree):

Also remove unncesssary sibling invalidation. It is a leftover from old pseudo-class invalidation code.

* Source/WebCore/dom/Node.cpp:
(WebCore::Node::adjustStyleValidity):

Make renderer invalidity a style flag.

(WebCore::Node::invalidateStyle):

Also add an invalidation mode for newly inserted nodes. Those will always need to invalidate the renderer and the ancestor chain.

(WebCore::Node::insertedIntoAncestor):
* Source/WebCore/dom/Node.h:
(WebCore::Node::needsStyleRecalc const):
