There were many comments on the original RFC about escaping regions that weren't counting on that behaviour. Do we make any guarantees now?

Would it escape _any_ region? What about:

```mlir
loop {
  my_fialect.op {
    if {
      linalg.generic {
        break N
      }
    }
  }
}
```

Even if we only have all these guarantees for SCF regions, then why do we even need a new loop op?
