According to ES6 spec: Built-in functions, strict functions created using the Function constructor, generator functions created using the Generator constructor, and functions created using the bind method also must not be created with such own properties(caller & arguments).

JSC doesn't create "caller" / "arguments" on all above-mentioned functions for a few years now (tested on r277026).
I am adding these test cases as part of https://bugs.webkit.org/show_bug.cgi?id=225277.
