[JSC] Adjust IC initial countdown
https://bugs.webkit.org/show_bug.cgi?id=251905
rdar://105165183
Reviewed by Keith Miller and Mark Lam.
This patch adjusts IC's countdown number (which is used before starting
generating IC).
We accidentally found that the current number "8" is not optimal in terms of
performance.
By exhaustive parameter searching, we found that "4" for initial count is
better.
It improves Speedometer2.1 by 0.54% and JetStream2.1 by 0.66%.
