[PATCH] RegAllocGreedy: Allow target to specify register class ordering.

The latest revision states this in the comments:

"Classes with high priority are assigned first."
and
"Classes with high priority should be assigned first by register allocators
with a greedy heuristic. The priority is a value in the range [0,63]."
There is no menioning of "larger" any longer, I hope that is good enough.
