patch 9.0.2160: instanceof() should use varargs as second arg

Problem:  instanceof() should use varargs as second arg
Solution: Modify `instanceof()` to use varargs instead of list

Modify `instanceof()` to use varargs instead of list
Valid `instanceof()` arguments are `type`s. A `type` is not a value;
it cannot be added to a list.

This change is non-compatible with the current usage of instanceof;
but instanceof is relatively new and it's a trivial change.

fixes: #13421
closes: #13644
