Log Message:
PR kern/40213 my i386 machine can't boot because of tsc

- Patch in atomic_cas_64() twice. The first patch is early and makes it
  the MP-atomic version available if we have cmpxchg8b. The second patch
  strips the lock prefix if ncpu==1.

- Fix the i486 atomic_cas_64() to not unconditionally enable interrupts.
