Jakob Stoklund Olesen ce0f9aef12 Don't run RAFast in the optimizing regalloc pipeline.
The fast register allocator is not supposed to work in the optimizing
pipeline. It doesn't make sense to compute live intervals, run full copy
coalescing, and then run RAFast.

Fast register allocation in the optimizing pipeline is better done by
RABasic.
