Message:

Optimize fetching the Node for never-anonymous renderers.
<​https://webkit.org/b/121627>

Reviewed by Antti Koivisto.

Add a RenderObject::nodeForNonAnonymous() that can be used instead
of node() when a renderer is guaranteed non-anonymous.

Use this to implement reference element getters for the various
renderers that are known at compile-time to correspond to a DOM node.

Also renamed existingElement() => element() since using an alternate
name for a reference overload isn't actually necessary.
