[Mesa-dev] [PATCH 00/18] anv: Remove the HiZ restriction on input attachments

[Nanley Chery]

Allow HiZ for input attachment-capable depth/stencil buffers. Do so
without requiring sampling operations on such attachments to go through
the HiZ buffer.

Series sections:
* Patch 1: Fix a bug.
* Patch 2: Add a new layout to aux_usage function.
* Patches 3-6: Refactor.
* Patches 7-10: Don't sample the depth buffer through HiZ.
* Patches 11-18: Allow HiZ on input attachment-capable depth/stencil
                 buffers.

This series increases the average frame rate on a release candidate of a
proprietary Vulkan benchmark by an average of 9.94% over 3 runs on my
SKL GT4.
