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().
4. Let baseValue be ? env.GetSuperBase().
5. Let bv be ? RequireObjectCoercible(baseValue).
6. Return a value of type Reference that is a Super Reference whose base
value component is bv, whose referenced name component is propertyKey,
whose thisValue component is actualThis, and whose strict reference flag
is strict.
