Fix Trac #9815
Dot-dot record-wildcard notation is simply illegal for constructors
without any named fields, but that was neither documented nor checked.
This patch does so
- Make the check in RnPat
- Add test T9815
- Fix CmmLayoutStack which was using the illegal form (!)
- Document in user manual
