Ah, no, we start from `emitc` + our dialect directly, most of the time. We just need a way to declare something that will result in `switch` pattern, whether it'll be through the `cf.switch`, `scf.index_switch` or `emitc.switch` doesn't really matter, though, the version with just `break;` patterns will be preferred.

I just know that we'll need to patch emitter in the end of the day, so it should go upstream.
