We are currently emitting object files that contain both final code
and IL.  I believe this is wasteful and does not really serve a useful
purpose.  However, I think we started emitting hybrid object files for
some reason.  Does anyone remember why?

If the version of GCC being used isn't compatible with the version of the IL in the object file, we can just fall back on the final code.

Whether that's still applicable to the current form of the IL being emitted is something you'll have to answer yourself.
