Bryce> You can use _Jv_IsInstanceOf(object, class)

Usually we recommend only using "Jv" functions and not "_Jv_"
functions.  The former are exported and the latter are not.

I recommend using Class::isInstance.

Lately I've been thinking gcjh could generate a per-class inline
function named something like "$class"; I got this idea because
apparently javac generates an internal function named "class$" to
implement the ".class" notation.

Comments?  Naming here is the big problem, as I see it.
