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.
