[PATCH] D11880: AMDGPU/SI: Only look at live out SGPR defs

It doesn't look like phab picked up your email response, so I'm reproducing it here:

> I’m not sure I see why. vreg0 is live out of the entry block, so it will have it’s range extended until after the endif, so I don’t think it can be assigned to the same register as vreg1


Ok, so you are saying this won't be a problem as long as we correctly extend the live range of vreg0.  That makes sense.  I would like to test this patch before it is committed.
