Tweak the register allocator priority queue some more.
New live ranges are assigned in long -> short order, but live ranges that have
been evicted at least once are deferred and assigned in short -> long order.
Also disable splitting and spilling for live ranges seen for the first time.
The intention is to create a realistic interference pattern from the heavy live
ranges before starting splitting and spilling around it.
