Consider this program:

$ cat a.c
void g(int x) {}
void f(int x);
int main(int argc) {
  if (argc) {
    int x = 42;
    f(x);
  } else {
    int y = 13;
    f(y);
  }
}

$ cat b.c
extern void g();
void f(int x) {
  if (x) {
    int y = x + 3;
    g(y);
  } else {
    int w = x + 4;
    g(w);
  }
}

This program is interesting because there are two TUs, and each TU has nested
scopes. Make sure we get the right parent and end offsets.
