 LLVM has the following intrinsics for working with AES encryption;

 @llvm.x86.aesni_{aesimc,aesenc,aesenclast,aesdec,aesdeclast,aeskeygenassist}

 It would be nice if at some stage these are supported through
 primops/intrinsics, as it would mean the crypto libraries can be rewritten
 to not use C and we'd get some nicer inlining on these.
