We need a better name somehow...

BTW what are the checks associated with this JSValueValue? What happens if you
pass a SMI?

Done.
As discussed offline: There are intentionally no checks, all intrinsics are
unsafe by definition. What we probably should do in the future is to have some
kind of type annotation which can be checked in debug builds.
