9.3.2 CreateBuiltinFunction(realm, steps, prototype, internalSlotsList) Abstract Operation
Step 5 needs to set the [[Prototype]] internal slot directly instead of calling the [[SetPrototypeOf]] internal method. Otherwise MakeArgGetter and MakeArgGetter creation can be observed by user code, for example when the [[Prototype]] of Object.prototype is a user-created Proxy object.
