This revision now requires changes to proceed.

Instead of moving this to a `.compile.pass.cpp`, I'd like to add an actual runtime test that the dtor does the right thing. Something like this:

  struct TrackDtor {
    bool* dtorCalled_;
    constexpr explicit TrackDtor(bool* dtorCalled) : dtorCalled_(dtorCalled) { }
    TEST_CONSTEXPR_CXX20 ~TrackDtor() { *dtorCalled_ = true; }
  };
  
  TEST_CONSTEXPR_CXX20 bool test() {
    bool called = false;
    {
      std::tuple<TrackDtor> tuple(TrackDtor(&called));
      assert(!called);
    }
    assert(called);
  
    return true;
  }
  
  int main(int, char**) {
    test();
  #if TEST_STD_VER > 20
    static_assert(test());
  #endif
    return 0;
  }
