kernel - Increase machdep.cpu_idle_repeat from 4 to 750

* Increase machdep.cpu_idle_repeat from 4 to 750.  It now takes longer
  before the kernel will move from HLT/MONITOR/MWAIT to ACPI-based halting.

* Improves benchmark performance significantly on recent cpus without
  eating up too much extra power, but laptop tests are still pending.

* Laptop users can always set it back to 4.
