[JSC] Handle 3 fiber rope string resolution efficiently
https://bugs.webkit.org/show_bug.cgi?id=285215
rdar://142119083
Reviewed by Yijia Huang.
This patch makes 3 fiber rope string resolution more efficient.
1. When the first fiber (fiber0) is rope, then we do rope resolution
without going to the slow path when stack height is enough.
If it is not a rope, then we just spread it into the result buffer.
2. Then, we use 2 fiber rope string resolution with the remaining
fibers.
