I was thinking about measuring whether 64bit aes is really faster
than i386 one. i386 code seems to be already maxed out (at the first
glance), apart from using stack for temp storage. I wonder why
64bit one is completely different, and it worth testing -
maybe i386 code (only with saves to REX registers instead of stack)
will actually work faster in 64bit too.
But twofish and camellia are higher on my TODO list.
