------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
Randomness strikes again, but a win overall.
Many of these above cases can be further improved by using inline assembly - it
is faster to try an arithmetic operation and check carry and overflow flags
than to check if it can be run.
