John Baldwin 7f7f6f85a1 Add a custom implementation of cpu_lock_delay() for x86. 
Avoid using DELAY() since it can try to use spin locks on CPUs without
a P-state invariant TSC.  For cpu_lock_delay(), always use the TSC if
it exists (even if it is not P-state invariant) to delay for a
microsecond.  If the TSC does not exist, read from I/O port 0x84 to
delay instead.
