I don't know how realistic this is, but I might have a function that
looks like this:

void recurse_and_jump(int n) {
  if (n > 0) {
    // do something interesting
    recurse_and_jump(n-1);
  } else
    exit(0); // or any other noreturn thing
}

This function is technically noreturn and would benefit from a tail call
opt.
