What is the common use case? Making sure some funtion is always
optimized or making sure it never optimized? If the second one, I
wonder if marking it cold would be a good enough approximation.

If we do need to enabled/disable passes run in each function, I would
suggest starting by proposing which attributes should be added to the
language reference.
