SHA2 is indeed in there. We should update them but I just tried a build
--with-icc-asm on Super and it seems to work like a champ (well it
doesn't emit build warnings and it passes all self-tests). Raw MD4 and
MD5 are significantly faster while Raw SHA1 is slower although this was
an OMP build running one thread. SHA2 is slower (it's not interleaved -
icc's superior speeds are from interleaving better).
