PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency.
...
UnitsSharePred was a source of randomness in the scheduler: node
priority depended on the queue data structure. I rewrote the recent
VRegCycle heuristics to completely replace the old heuristic without
any randomness. To make these heuristic adjustments to node latency work,
I also needed to do something a little more reasonable with TokenFactor. I
gave it zero latency to its consumers and always schedule it as low as
possible.

Changing allocation ordering from r3 ... r0 back to r0 ... r3. The order change no longer make sense after the coalescing changes we have made since then.
