Implements a workaround for HSDES#14014414195. Note that this change
deviates heavily from the workaround suggested in the HSDES, since all
of the suggestions are either costly at runtime or outright
non-compliant, so they would require us to apply the workaround
selectively for affected applications.
Instead of adding hacks to the compiler that manually implement the
LOD computation of 3D texturing operations in the shader, initialize
an extra sampler state structure in the driver that has anisotropic
filtering forced off, and use it instead of the normal sampler state
structure whenever a 3D texture is bound to the same sampler unit.

For non-discard writes, we need to make sure that the resource has valid contents
so they can be *updated*, not overwritten.
We have to skip this when doing asynchronous maps, but that should be okay, because
the threading context should only do asynchronous map-write when the resource is
known to be idle/empty.

In the case of a multi-stream GS that is attempting to output wide
points to stream 0, we can support this by lowering stream 0 to
triangles and then removing the other streams. This is only valid
to do if the other streams are not being written to stream output,
either if they're not present in the SO info or no buffer is bound.
Fixes the arb_gpu_shader5/arb_gpu_shader5-emitstreamvertex_nodraw
piglit test which does this.

I couldn't find this in a spec but the builtin-gl-sample-mask piglit
seems to expect writing to the output sample mask to do nothing when
max num samples == 0.
The ForcedSampleCount property should make everything appear as if
MSAA is disabled. However, it's undefined behavior if depth is
bound, so in that case, we can at least use a lowering pass to
make things *look* like MSAA is off, unless you use atomics to
count invocations.

The first container stage ("build") is for dependencies of the build.
These are infrequently-changing things like Visual Studio, LLVM, git,
and also meson. The second container stage ("test") currently depends
on the first, and adds test dependencies like piglit.
This lets us rev piglit without having to rebuild LLVM.

EXT_vertex_input_dynamic_state
When both EXT_vertex_input_dynamic_state and EXT_extended_dynamic_state
are not available stride is never set and nothing is rasterized as all
triangles are degenerate.
This fix copies stride into the VkVertexInputBindingDescription array
when the graphics pipeline is created when those extensions aren't
available.

This was identified by Coverity. 4bb9c0a28a added uses of a third
address register, but the arrays for tracking address registers only
have two slots.
Add back a version of the assertion from before 4bb9c0a28a to help
prevent future problems. I don't think any drivers that would hit
this path use NIR-to-TGSI yet, so it may be moot.

this one's a bit tricky since vulkan doesn't support vec5, the return from
the instructions is a struct, and I don't want to add temp var support to zink
now instead the process for these ops is:
* rewrite the is_sparse_texels_resident instruction to read the first vec member of the texop
* (temporarily) decrement num_components for sparse texop's dest to get real result size
* wrap texop's return type in spirv-required struct(uint, result)
* unwrap struct, store result normally + store residency info to separate array
* for is_sparse_texels_resident, ignore the mov alu for src[0] and instead use the ssa index
from the parent instr since this is the original texop that was used to store the residency result

This helps non-native-integers hardware where relative addressing of UBOs
has a constant offset field, and having addressing math (particularly for
D3D9) emitted as ALU ops ends up running us out of constants. For
native-integers drivers (such as softpipe), the possible-overflow check
typically triggers and we end up not folding.
