DXIL doesn't support a single varying having components belonging
to multiple streams. For geometry shader outputs, whenever we find
this to be the case, break up that variable into multiple sub-
variables, and update stores to that variable to write to the new
sub-variables instead.

This pass was originally written for d3d12, but is useful for hardware

Also rename the lowering pass and some surrounding code to
nir_lower_tex_shadow as suggested by Emma.
I'd like to use the pass that's already in tree.

When multiple variables are packed into the same location, we need
to re-construct variables that read/write the same components of that
register so that the DXIL signature is correct. We could try to
merge these variables, but getting the types right sounds harder than
just preserving the multiple individual variables.

GLSL puts a bunch of tessellation info in the eval shaders, because
passthrough control shaders can exist. D3D12 puts it in the control
(hull) shader instead. So, when specializing, copy info from domain
to hull. For initial compiles (no domain shader), just make something
up.
D3D12 also requires the domain and hull shaders to have identical
patch constant signatures. Use the existing infrastructure and extend
it to also propagate patch constants. Notably, patch constant locations
are outside of the 64-bit range value so they require a separate pass
to avoid shifts larger than 64.

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

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.

This is handled in 2 ways:
* For casts in the same "class," we can just do the cast. There's also
limited support for 4x8 => 1x32 and 2x16 => 1x32.
* For casts that are just by size, use a lowering pass. This reads the
data in the appropriate UINT format (except R11G11B10), retrieves
the original bits, re-packs it into the dest, and returns it to the
app for loads. For stores, the process is done in reverse - bits
for the final format are computed and re-expanded to the format that
should be used for the store.

For GL, we've previously mostly ignored the binding property for sampler variables
during the shader compilation step. For CL, our image bindings were always 0-based as well.
Now, for Vulkan, we are going to be getting explicit bindings and need to emit DXIL that
respects those bindings. Since Vulkan can also have both split and combined images and samplers,
we now need to be smarter about recognizing when NIR is trying to use a "sampler" as *both* an
image and sampler (in deref mode, the same variable will be deref'd as both image and sampler).
That "being smarter" bit comes next, but first, let's prep GL for building correct root
signatures and binding the resources correctly.

The prog_to_nir->NIR-to-TGSI change ended up causing regressions on r300,
and svga against r300-class hardware, because nir_lower_uniforms_to_ubo()
introduced shifts that nir_lower_ubo_vec4() tried to reverse, but that NIR
couldn't prove are no-ops (since shifting up and back down may drop bits),
and the hardware can't do the integer ops.
Instead, make it so that nir_lower_uniforms_to_ubo can generate
nir_intrinsic_load_ubo_vec4 directly for !INTEGER hardware.

SPIR-V would produce rather than the GLSL compiler. It also means
we can delete the current fixup pass, since previously clip distance
was always float4s but some components could go unused. Now, clip
distance is an array that's appropriately sized for what's actually
