turnip: Fix vkGetQueryPoolResults with available flag

Previously, calling vkGetQueryPoolResults with the
VK_QUERY_RESULT_WITH_AVAILABILITY_BIT flag set the query result
field in *pData to 0 if unavailable and the query result if
available. This was a misunderstanding of the Vulkan spec, and this
commit corrects the behavior to eriting a separate available result
in addition to the query result.

nir: Make nir_deref_path_init skip trivial casts

In a NIR generated using SPIR-V initializers to variables, copy
propagation can end up transforming

    vec1 32 ssa_33 = deref_var &@1 (shared mat2x4)
    vec1 32 ssa_35 = mov ssa_33
    vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_35 (shared mat2x4)  /* ptr_stride=0 */

    vec1 32 ssa_33 = deref_var &@1 (shared mat2x4)
    vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_33 (shared mat2x4)  /* ptr_stride=0 */

Before the optimization, the "head" of a path of deref that uses ssa_7
will be the cast.  After, it will be the variable in ssa_33.  Since
the types are the same, this is a trivial cast that would be picked up
by nir_opt_deref.

If we need to compare such deref-chain after optimization with another
deref-chain for the same variable, the compare function will get
confused by the cast in the middle.

One alternative would be to add nir_opt_deref to places that compare
derefs, but that might not scale well, so skip the trivial casts when
generating the paths instead.

radv/gfx10: implement NGG GS queries

The number of generated primitives is only counted by the hardware
if GS uses the legacy path. For NGG GS, we need to accumulate that
value in the NGG GS itself. To achieve that, we use a plain GDS
atomic operation.

anv: Rename a variable

anv/block_pool: Ensure allocations have contiguous maps

Because softpin block pools are made up of a set of BOs with different
maps, it was possible for a single state to end up straddling blocks.
To fix this, we pass a contiguous size to anv_block_pool_grow and it
ensures that the next allocation in the pool will have at least that
size.

We also add an assert in anv_block_pool_map to ensure we always get
contiguous maps.  Prior to the changes to anv_block_pool_grow, the unit
tests failed with this assert.  With this patch, the tests pass.

This was causing problems on Gen12 where we allocate the pages for the
AUX table from the dynamic state pool.  The first chunk, which gets
allocated very early in the pool's history, is 1MB which was enough that
it was getting multiple BOs.  This caused the gen_aux_map code to write
outside of the map and overwrite the instruction state pool buffer which
lead to GPU hangs.

zink: set compareEnable when setting compareOp

We need to enable compareEnable for compareOp to be valid, and ANV was
recently updated to respect this. So let's update Zink to match.

This fixes the shadow-variants of several piglit regressions, like these:
spec@arb_shader_texture_lod@execution@tex-miplevel-selection
spec@glsl-1.20@execution@tex-miplevel-selection

Fixes: a19cdf989b1 ("anv: only use VkSamplerCreateInfo::compareOp if enabled")

ci: Enable -Werror on the meson-i386 build.

I find warnings to be very disruptive to my workflow (using emacs's "go to
next error" feature), and I periodically have to go clean up other
people's drivers to get back to finding my own warnings in the noise.  I
know I'm not the only one doing something like this.

We don't want to enable -Werror by default in builds, since it means that
end users will have builds spuriously fail based on what compiler version
and opt flags they have compared to what the devs are using.  However, it
is quite easy to have CI ensure that we at least don't introduce warnings
on the compiler version that it uses.

For now I've just enabled it on meson-i386 to cover a bunch of Mesa core
and get us started on ratcheting up warnings-cleanliness in the tree,
without me having to fix up all the drivers at once.
