[JSC] Suppress StringCharAt when OutOfBounds exit happens frequently
https://bugs.webkit.org/show_bug.cgi?id=258542

Reviewed by Mark Lam.
We can do this better, but let's first do very easy fix. This patch avoids
using StringCharAt DFG node
when OutOfBounds OSR exits happen very frequently. This avoids repeated OSR
exit when OutOfBounds happens.
