  When the base of a property reference is primitive, it is coerced to an
  object during value retrieval

  5. If IsPropertyReference(V) is true, then
     a. If HasPrimitiveBase(V) is true, then
        i. Assert: In this case, base will never be null or undefined.
        ii. Let base be ToObject(base).
     b. Return ? base.[[Get]](GetReferencedName(V), GetThisValue(V)).
