Can we make this assert exactly how lon the array is?

> JSTests/stress/object-entries.js:116
> +Array.prototype.push = function () { throw new Error("Array.prototype.push should not be used during invoking of Object.entries.")};

This is a good test. Can you also add one where you replace Reflect.getOwnPropertyDescriptor
to make sure the algorithm doesn't call that?
