We were allocating registers into the MRF hack region, resulting in

corresponding GRFs, and tracking the live intervals of the "MRF"s and
setting up the conflicts. But this is way easier for the moment.

Ugh. :( Thanks for taking care of this. I agree that this is the best
approach for now.

I am a bit concerned, though: why would it register allocate out of the
top 16 GRFs unless it needed that many? By lowering the ceiling, won't
we run out of registers entirely? We don't support spilling on Gen7
yet...I've been meaning to get around to implementing that.
