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).
