A small change to this patch allows it to be cleanly backported to
stable without all of Ben's pathches. All that's needed is to replace
intel_miptree_hiz_buffer with intel_miptree_aux_buffer.

I respun these patches for the 12.0 branch and 13.0 branch and sent
separate series for each; one to "12.0" <mesa-stable at ...> and one to
"13.0" <mesa-stable at ...>. Those series should apply to each branch with
no conflicts.

In the future, when I submit a patch series for a specific stable
branch, how should I denote the branch?
