 --> (https://bugs.webkit.org/attachment.cgi?id=25832&action=view)
share primitive value instances

A more stylish solution than sharing would be to turn CSSPrimitiveValue (or
CSSValues in general) into non-virtual, non-refcounted simple type with value
semantics. In practice these sharing tricks get similar memory benefits with
less need for refactoring.

This does not directly depend on the previous patch (as the parent field of
CSSValues is never used) thought it depends on it conceptually to facilitate
sharing.
