Following up on Darin Adler's remark in bug 146852, comment 5, we should remove the default constructor for WebCore::Pair as we are not making use of it. Similarly, we can remove the setters Pair::setFirst() and Pair::setSecond() since this are unused and it seems weird to expose such setter when we do not have a default constructor.
