Test case

Overloaded functions currently do argument checks before the this object check, which leads to the exceptions being thrown in the wrong order.

*supported*

My personal preference would have been Operation2Body rather than OperationBody2.

> +static inline JSC::EncodedJSValue jsTestInterfacePrototypeFunctionSupplementalMethod2Body(JSC::ExecState* state, typename IDLOperation<JSTestInterface>::ClassParameter castedThis, JSC::ThrowScope& throwScope)

Notice that the format here is Method2Body, not MethodBody2.
