            <rdar://problem/8363003> REGRESSION: ~1.4% sunspider regression in
            interpreter due to 54724 and 54596
    
            Fixed a typo (using "UNLIKELY" instead of "LIKELY").
    
            * wtf/PassRefPtr.h:
            (WTF::refIfNotNull):
            (WTF::derefIfNotNull): It is likely that m_ptr != 0 because most RefPtrs
            hold real data. Also, in cases where they do not hold real data, the
            compiler usually sees a call to release() right before the call to the
            destructor, so it can probably optimize out the test completely.
