ALPHA[3-6] works, ALPHA[78] fails as reported in the ticket

Can you try an earlier alpha for me?  Specifically A3, I think this
may be some hand optimization of memmov stuff that included a new
instruction that we did not use before.

I saw the original posting by phk and was going to try and validate
it here on my x230, which might narrow this down to an AMD only issue,
or a "we starting using new instructions" issue.  But time has gotten
far away from me and was not able to do that.

I do know that I ran an earlier 12.0Alpha3 on my 11.1 x230 laptop
without issue.

I did see the PR when it was opened.  Hopefully the right people can
take a look at this relatively soon.

I tried running 12.0-BETA8 under bhyve on a Phenom-II+11.2 box and
it explodes because of an unemulated instruction:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=232081

I have no idea what importance this has in relation to releasing 12.0
