Don't warn on fall-through from unreachable code.
Summary:
A motivating example:
class ClassWithDtor {
public:
~ClassWithDtor() {}
};
void fallthrough3(int n) {
switch (n) {
case 2:
do {
ClassWithDtor temp;
return;
} while (0); // This generates a chain of unreachable CFG blocks.
case 3:
break;
}
}
