----------------
Can you also add some tests that use nested loops with multiple levels of `break` and `continue` use?

Also, I think it might be useful to show the jump statements causing code to be an invalid constant expression, as in: 
```
constexpr int foo() {
  int i;

  do {
    break;
    i = 12;
  } while (1);

  return i;
}

constexpr int f = foo();
```
