  SuperProperty evaluation when "this" binding has not been initialized
info: |
  [...]
  4. If the code matched by the syntactic production that is being evaluated is
     strict mode code, let strict be true, else let strict be false.
  5. Return ? MakeSuperPropertyReference(propertyKey, strict).

  12.3.5.3 Runtime Semantics: MakeSuperPropertyReference

  1. Let env be GetThisEnvironment( ).
  2. If env.HasSuperBinding() is false, throw a ReferenceError exception.
  3. Let actualThis be ? env.GetThisBinding().

  8.1.1.3.4 GetThisBinding

  1. Let envRec be the function Environment Record for which the method was
     invoked.
  2. Assert: envRec.[[ThisBindingStatus]] is not "lexical".
  3. If envRec.[[ThisBindingStatus]] is "uninitialized", throw a ReferenceError
     exception.
