* Can I add a new built-in macro __builtin_secure_generate_random(void* data, std::size_t size) for C and C++ on hosted GCC platforms that support it?

I think compiler time random number is useful for cryptography things like blinding.
This built-in should also be constexpr.
On platforms that does not support this feature (MSDOS) do not define this __builtin.
Users can use
#if __has_builtin(__builtin_secure_generate_random)
#endif
to detect whether this feature is supported.
