This looks like an internal glibc header, is there a strong reason to add this?

Note that we use slightly different wording / definitions in libc/include/__llvm-libc-common.h (`__BEGIN_C_DECLS`, `__END_C_DECLS`, `__NOEXCEPT`), and `throw()` is deprecated in C++11 and later. I would suggest to exclude `<sys/cdefs.h>` from this PR, as it warrants some discussion. The other two are non-controversial (to me, at least).
