This is helpful for D74949 <https://reviews.llvm.org/D74949>, but `_Noreturn` is not recognized by C++ compilers, a solution is to include <stdnoreturn.h> which will define `noreturn` only as `_Noreturn` for C. So using `NoReturn` would also require we make sure include <stdnoreturn.h> which is possible but perhaps not ideal.
Do we have any obligation to support prior to C11? If so then <stdnoreturn.h> would not be an option we would just have to make our own header, which is not difficult.
It's worth mentioning that a quick test on compiler explorer of MSVC suggests that they don't support _Noreturn or stdnoreturn.h even with `-std=c11`, but I don't think the burden should be on us to work around non conforming compilers.
