[JSC] Do not release scope while it is used before forEachInIterationRecord
https://bugs.webkit.org/show_bug.cgi?id=315927
rdar://178332419
Reviewed by Yijia Huang.
forEachInIterationRecord's lambda was using scope even after calling
`scope.release()`,
which incorrectly suppressing the exception checks. This patch makes
SetPrototype.cpp code more idiomatic: use a new scope inside lambda, and
do scope.release() only when we no longer use scope.
