cc0ada2d67 anv: dynamic state for polygon mode
Remove 'polygon_mode' from pipeline and read it from
dynamic state instead.

This affects following packets:

  3DSTATE_CLIP
  3DSTATE_RASTER

c0c243f1cb anv, iris: Disable pre fetching the binding table entries on DG2
On DG2 the HW will fetch the binding entries into the cache
for every single thread when a compute walker is dispatched,
wiping out the advantages of the cache prefetch.

The spec also advises to not do a cache prefetch when we have more than
31 binding table entries, but most real world applications will never
hit that limit.

Instead of this fragile use_primitive_replication bit which we set
differently depending on whether or not we pulled the shader out of the
cache, compute and use the information up-front during the compile and
then always fetch it from the vue_map after that.  This way, regardless
of whether the shader comes from the cache or not, we have the same flow

4eaecd7965 anv: disable task redistribution
If task redistribution is enabled, then some mesh shaders read
garbage from task payload.

It may be a hardware bug, or it may be our bug. Who knows :(

This change will probably negatively affect performance of task
shader-enabled workloads on multi-slice GPUs, because mesh shaders
will be executed only on the slice where task shader was spawned.

9ecc26ff27 anv: Do depth/stencil optimization for dynamic depth/stencil
When we made depth/stencil dynamic, we lost the optimization.  This is
particularly important for cases where the stencil test is enabled but
never writes anything as certain combinations with discard can cause
the stencil write (which doesn't do anything) to get moved late which
can be a measurable perf hit.  According to 028e1137e6 ("anv/pipeline:
Be smarter about depth/stencil state", it was a couple percent for DOTA2
on Broadwell back in the day.  No idea how it affects current titles.

This may also improve the depth/stncil PMA workarounds on Gen8 and Gen9
since they're now looking at optimized depth/stencil state.

dfedeccc13 intel: Only set VectorMaskEnable when needed
For cases with lots of very small primitives, this may improve
performance because we're not executing those dead channels all the
time.

Shader-db reports no instruction or cycle-count changes.  However, by
hacking up the driver to report when this optimization triggers, it
appears to affect about 10% of shader-db.

v2 (Kenneth Graunke): Always enable VMask prior to XeHP for now,
because using VMask on those platforms allows us to perform the
eliminate_find_live_channel() optimization.  However, XeHP doesn't
seem to have packed fragment shader dispatch, so we lose that
optimization regardless, and there's no reason not to avoid vmask.

168b13364f anv: rework sample location
On Gfx7 we can only give the sample location for a given multisample
number. This means everytime the multisampling value changes, we have
to re-emit the locations. It's fine because it's also where
(3DSTATE_MULTISAMPLE) the number of samples is stored.

On Gfx8+ though, 3DSTATE_MULTISAMPLE only holds the number of samples
and all the sample locations for all number of samples are located in
3DSTATE_SAMPLE_PATTERN. So to be more effecient there, we need to
track the locations for all sample numbers and compare new values with
the relevant sample count when touching the dynamic state.

a4f502de32 anv: fix VK_DYNAMIC_STATE_COLOR_WRITE_ENABLE_EXT state
First, there is a problem if you do the following

 vkCmdSetColorWriteEnableEXT(attachmentCount = 8)
 vkCmdBindPipeline(GFX, with attachmentCount = 4)
 vkCmdDraw()
 vkCmdBindPipeline(GFX, with attachmentCount = 8)
 vkCmdDraw()

Because in the dynamic state emission code we rely on the first
pipeline to figure the number of BLEND_STATE entries to prepare. This
is wrong, we should fill all entries so that the dynamic state works
regardless of the number of attachments in the pipeline. With regard
to the dynamic values, we should retain enable/disable values that do
not concern the current pipeline.

Second, 3DSTATE_WM was not always reemitted when the pipeline changed.
But since it is not emitted as part of the pipeline, this results in
inconsistent state being programmed.

Third, we end up disabling the fragment stage completely in some
cases. And that is programming the pipeline inconsistently and
triggering a hang on TGL.
