V0033: Object.prototype.__proto__.set.name is undefined

The specification states:

 B.2.2.1.2 set Object.prototype.__proto__
  
     The value of the [[Set]] attribute is a built-in function that takes an argument 
     proto. It performs the following steps:
  
         1.  Let O be RequireObjectCoercible(this value).
         2.  ReturnIfAbrupt(O).
         3.  If Type(proto) is neither Object nor Null, return undefined.
         4.  If Type(O) is not Object, return undefined.
         5.  Let status be O.[[SetPrototypeOf]](proto).
         6.  ReturnIfAbrupt(status).
         7.  If status is false, throw a TypeError exception.
         8.  Return undefined.

The specification states:

 B.2.2.1.1 get Object.prototype.__proto__
  
     The value of the [[Get]] attribute is a built-in function that requires no arguments. 
     It performs the following steps:
  
         1.  Let O be ToObject(this value).
         2.  ReturnIfAbrupt(O).
         3.  Return O.[[GetPrototypeOf]]().
