Hi Fedor,

can you make an example where a pass actually needs to opt-out? Because IMO, bisect should quite literally to DebugCounter-style skip every step in every ::run method's loop. Passes should not even be concerned with this.

This isn't so much an issue for the optimization pipeline, but code generation involves some passes which are mandatory (e.g. isel).
