Nit: for completeness' sake, this also needs:
```
// UNSUPPORTED: c++03
// XFAIL: libcpp-hardening-mode=debug && availability-verbose_abort-missing
```
(due to the way `check_assertion.h` is implemented). I plan to add a new feature like `has-check-assertion` to wrap all those checks together, but for now it all has to be marked explicitly in tests relying on `check_assertion.h`.
