[JSC] Bound function optimization is observable with instanceof
https://bugs.webkit.org/show_bug.cgi?id=253634
rdar://106498460
Reviewed by Alexey Shvayka and Mark Lam.
Target function is used only when bound function is used for instanceof.
We keep the original target function when flattening bound functions, and
use it only when instanceof is used.
* JSTests/stress/bound-function-target.js: Added.
