There are still some tests that require argument.caller to exist and to be poisoned

[hermanventer]

As per tc39/ecma262#689, the requirement to poison arguments.caller has been removed from the standard.

#797 was supposed to remove all references to arguments.caller from the test suite, but built-ins/Function/StrictFunction_restricted-properties.js still requires poisoned pill behavior for arguments.caller.

[leobalter]

the test/built-ins/Function/StrictFunction_restricted-properties.js file is checking for caller and arguments applied to function objects by AddRestrictedFunctionProperties and also mentioned in the Forbidden Extensions section.

Those are not the same poison as the previous arguments.caller.
