If we want to support changes in the environment, I think it would be
an impossibly high bar for such a minor feature.

So perhaps the following would be enough:

  . find the source .el file of the compiled function
  . compile it into a temporary file and disassemble the result
  . delete the compiled temporary file

Out of the alternatives you proposed only #3 is to some extent
acceptable, but it is too complicated, IMO.
