fix two heuristics in rega

There was a typo that made always the same successor
to be selected for register allocation hinting.
Also, I now attempt to prioritize hints over succeccor's
choices as it appears to give slightly better results...

Now that I think about it, the code re-using the most
frequent successor block's assignment might be dead
because all registers have hints if they got assigned
once.  To investigate.
