anv/cmd_buffer: Enable rendering to HiZ
Nanley Chery:
(rebase)
- Resolve conflicts with new anv_batch_emit macro
(amend)
- Handle a QPitch TODO
- Emit 3DSTATE_HIER_DEPTH_BUFFER on pre-BDW systems
- Only use HiZ for single-subpass renderpasses
- Emit the HiZ instruction before the stencil instruction to follow the
optimized clear sequence specified in the PRMs
- Don't modify clear params
- Enable resolves when a HiZ buffer is used to ensure depth buffer validity
Provides an FPS increase of ~15% on the Sascha triangle and multisampling
demos.
