- @jhuber6: replaced NDEBUG with [[maybe_unused]]
- @yxsamliu: HasEmptyDtor now checks the base element type of an array and added the tests. Note this also rejects namespace scope __device__/__constant__/__shared__ arrays with elements with a non-empty destructor that were previously accepted
- @Sirraide: This patch only fixes 'b1' from #233925, so I'm holding off on adding the tests
