<pre>You can use _builtin_cpu_supports("aes") to check for AES-NI but you can't use
_builtin_cpu_supports("sha") to check for SHA-NI support in the CPU.
This builtin was invented by gcc and they are missing a way to check for sha as
well. I filed a bug with them, too. It would be great if both clang and gcc
added this.</pre>
