[JSC] Further optimize eval
https://bugs.webkit.org/show_bug.cgi?id=294592
rdar://153603343
Reviewed by Yijia Huang.
Direct call to `eval` can happen only form JS code execution in normal
execution. Thus we can avoid some unnecessary setup for executeEval.
This patch removes super costly operations in executeEval which is not
necessary for direct call to `eval`. We also clear scope of eval callee
instead of setting a global scope.
