    Retroactive derivative registration: register derivatives for functions in other modules.

    Previously:
    * If module A defines `func foo`, then its derivatives must be in the same module.

    With retroactive derivative registration:
    * If module A defines `func foo`;
    * And if module B imports module A and defines `@differentiating(foo) func derivativeFoo`:
    * Then module C can import modules A and B and differentiate `func foo` (e.g. via differentiation APIs).
