[LLVMdev] register scavenging
So what I realized is that you can't use the simple scavenger trick
where you create the virtual register and use the more advanced features.
This is because you can't call forward() in any form if there are
virtual registers being used by any of the instructions in the basic
block. This will cause forward to fail.
Maybe this is a bug in forward()
