Thanks for the PR @aniragil. I love to see that this seems to move work previously handled in the emitter to the dialect and dedicated conversions. We initially had an `emitc.if` as well as an `emitc.yield` op which where however duplicating the behavior of the corresponding scf ops. This looks much better to me.

Unfortunately, I am currently on a business travel and have only very little time to review. @simon-camp can you already take a first look?
