    14.5.10 Runtime Semantics: EvaluateBody

    1. Perform ? FunctionDeclarationInstantiation(functionObject, argumentsList).
    2. Let generator be ? OrdinaryCreateFromConstructor(functionObject, "%AsyncGeneratorPrototype%",
       « [[AsyncGeneratorState]], [[AsyncGeneratorContext]], [[AsyncGeneratorQueue]] »).
    3. Perform ! AsyncGeneratorStart(generator, FunctionBody).
