`o instanceof F` is more or less equivalent to recursively checking if
`o.__proto__.constructor === F`. That is, you can make objects pass
the instanceof test by making their constructors inherit from one
another. For example:
function A() {}
function B() {}
B.prototype = Object.create(A.prototype);
(new B) instanceof A; // true
You can accomplish the same thing with the C++ API in a number of
ways. In your case, just FunctionTemplate::Inherit() might be enough.
