`tests/CodeGen-Binding` is a full-stack integration jack for JNI
bindings, ensuring that `generator.exe` and company work as expected.
It is *somewhat* duplicative of the Java.Interop `generator` unit
tests, except these are actually executed, while the `generator` tests
are *not* executed.
`tests/CodeGen-MkBundle` is a test for the "Bundle assemblies into
native code" feature, but isn't part of the "proper" unit test
infrastructure, as it doesn't yet contain an `Instrumentation` type.
TODO: Add an `Instrumentation` type to `tests/CodeGen-MkBundle`.
