[arch-dev-public] i686 and SSE2

Actually, why don't raise the bar higher? SSE2 has been introduced in
2001 – that's 15 years to upgrade one's hardware and given my sad
experiences with computers, I find it hard to believe anyone has that
old PC that happens to run Arch.

We used to advertise ourselves as optimized for modern processors. Our
"i786" really should include SSE3. For the same reason I would not
complain about requiring SSE4 instructions for amd64.

pkgstats seems to have lots of old data. It would be beneficial to start
the statistics from scratch and include kernel modules as well to see if
our config isn't overloaded.
