Remove the @_downgrade_exhaustivity_check hack
...
This hack was only needed for Swift 3 mode in a narrow case. Flush it out of the compiler so we can simplify the space engine.

Clean up fix-it generation for missing cases, esp. with '@unknown'
...
- Combine the common logic for editor mode and non-editor mode.

- If '@unknown' is the only missing case, put `fatalError()` in the
Xcode placeholder, since that's what the compiler would have done.
