Strangeness in CreateArgumentsObject definition

Hi Oliver, I believe the spec is correct.
In non-strict mode, only callee is specified, although many implementations
may provide a de-facto caller as well.
In strict mode, both callee and caller are poisoned. arguments.caller is
poisoned in step 14.b as you noticed. On the next page, arguments.callee is
poisoned in step 14.c
