This test was added by #65177 which claims to be implementing [LWG3545](https://wg21.link/LWG3545), but that issue only said that `pointer_traits` should be SFINAE-friendly. It didn't require that `to_address` should be SFINAE-friendly.
There is a separate (and unresolved) issue about making `to_address` SFINAE-friendly: [LWG4058](https://wg21.link/lwg4058).
Until LWG4058 is resolved, this test is not portable and relies on a non-standard libc++ extension.
