8d22ab0e503ccaa464cbecd94d1059dbc5a61f4a ci: Enable address sanitizer (ASan) stack-use-after-return checking (practicalswift)

Pull request description:

  Enable address sanitizer (ASan) stack-use-after-return checking (`detect_stack_use_after_return=1`).

  Example:

  ```
  #include <iostream>
  #include <string>

  const std::string& get_string(int i) {
      return std::to_string(i);
  }

  int main() {
      std::cout << get_string(41) << "\n";
  }
  ```

  Without address sanitizer (ASan) stack-use-after-return checking:

  ```
  $ ./stack-use-after-return

  $
  ```

  With address sanitizer (ASan) stack-use-after-return checking:

  ```
  $ ASAN_OPTIONS="detect_stack_use_after_return=1" ./stack-use-after-return
