Rusty Russell b7e5f77916 Revert "x86: Side-step lguest problem by only building cmpxchg8b_emu for pre-Pentium" ...

commit db677ffa5f upstream.

This reverts commit ae1b22f6e4.

As Linus said in 982d007a6e: "There was something really messy about
cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it
carefully."

This breaks lguest for those configs, but we can fix that by emulating
if we have to.
