Agreed, that's a good idea.

At the moment similar mechanisms are:

- Declare a function with (declare (speed -1)) will include the
  function in the .eln but in byte-code form.

- Have comp-speed to -1 as file variable in the source file should
  produce an eln containing only byte-code functions.

But yeah, a dedicated cookie is better because there's no point of
producing the .eln file at all for cases like this.
