You should add tests for: `_Noreturn`, `inline`, `_Thread_local`, `constexpr`
(C23), `auto` (C23 usage, not C89 usage).
I think it also makes sense to add a test for `alignas` but I think we should
allow that in any position under the same logic for allowing attributes.
Also, please add a newline to the end of the file.
