   File Name:          8.6.2.1-1.js
   ECMA Section:       8.6.2.1 Get (Value)
   Description:

   When the [[Get]] method of O is called with property name P, the following
   steps are taken:

   1.  If O doesn't have a property with name P, go to step 4.
   2.  Get the value of the property.
   3.  Return Result(2).
   4.  If the [[Prototype]] of O is null, return undefined.
   5.  Call the [[Get]] method of [[Prototype]] with property name P.
   6.  Return Result(5).

   This tests [[Get]] (Value).
