Devirtualize CSSValue.
<http://webkit.org/b/71666>
Reviewed by Antti Koivisto.
Make the CSSValue destructor non-virtual (along with all the subclasses.)
This removes the vtables, and the pointers thereto in each value instance,
shrinking each object by one CPU word (4 or 8 bytes.)
We use the same trick as CSSRule to implement destruction; providing our
own deref() instead of RefCounted's, and performing a statically typed
delete in a destroy() method called when the ref count reaches 0.
Also made all the empty subclass destructors inline.
