Handle unstructured 'switch' statements such as Duff's device
- New elaboration pass: SwitchNorm
- recognizes structured 'switch' statements and puts them in a
normalized form;
- if selected, transforms unstructured 'switch' statements into a
structured switch with goto actions + the original switch body
with appropriate labels and gotos.
- C2C treatment of 'switch' statements is simplified accordingly.
- New language support option `-funstructured-switch`.
- Some tests were added (test/regression/switch3.c).
