Jakob Stoklund Olesen 98d9648de7 Change the RAGreedy register assignment order so large live ranges are allocated first. ...

This is based on the observation that long live ranges are more difficult to
allocate, so there is a better chance of solving the puzzle by handling the big
pieces first. The allocator will evict and split long alive ranges when they get
in the way.

RABasic is still using spill weights for its priority queue, so the interface to
the queue has been virtualized.
