Personally, I would expect that to compile, as it does right now. At least
based on my understanding of the docs
https://clang.llvm.org/docs/LanguageExtensions.html#checked-arithmetic-builtins.
Also, GCC isn't happy because it explicitly forbids bools
(https://gcc.gnu.org/onlinedocs/gcc/Integer-Overflow-Builtins.html), whereas
Clang explicitly allows them.
