We can cache lookups to JSScope::abstractResolve inside CodeBlock::finishCreation
https://bugs.webkit.org/show_bug.cgi?id=158036
Reviewed by Geoffrey Garen.
This patch implements a 1 item cache for JSScope::abstractResolve. I also tried
implementing the cache as a HashMap, but it seemed either less profitable on some
benchmarks or just as profitable on others. Therefore, it's cleaner to just
use a 1 item cache.
