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.

Keep track of the last place a live virtreg was used.

If we reload a virtual register that's already been assigned, we want to mark
...
that instruction as its "last use". This fixes PR1925.
