latency priority function.

Only enable this with -use-sched-latencies, I'll enable it by default with a
clean nightly tester run tonight.

PPC is the only target that provides latency info currently.

implementations of the same interface (priority computation) without touching
the scheduler itself.

having (future) PPC specific in this file is also wrong, but this is a
