           Summary: final switch error message should report all missing
                    enum members

When turning a normal switch into a final switch, I often go through this sequence:

- recompile
- Error: `enum` member `A` not represented in `final switch`
- add case for A
- recompile
- Error: `enum` member `B` not represented in `final switch`
- add case for B
- recompile
- Error: `enum` member `C` not represented in `final switch`

etc. It would be more convenient if the compiler didn't stop at the first missing member.
