It strikes me that this single intrinsic is extensible and just as easily
implemented as the JIT specific ones. And heads off a potentially messy
proliferation of ad-hoc methods right at the start.

Because an annotation that is seen by the JIT gives it the opportunity to
check the type of the declared instance with the VM structure it
corresponds to. I think dismissing annotations as syntactic sugar is a
bit unfair.
