Instead of building a constant mask (which depends on knowing the
subgroup size), we build an expression. Because the pass uses the
nir_shader_lower_instructions helper, subgroup lowering will be run on
any newly emitted instructions as well as the previously existing
instructions. In particular, if the subgroup size is known, the newly
emitted subgroup_size intrinsic will get turned into a constant and a
later constant folding pass will clean it up.

The rules for gl_SubgroupSize in Vulkan require that it be a constant
that can be queried through the API. However, all GL requires is that
it's a uniform. Instead of always claiming that the subgroup size in
the shader is 32 in GL like we have to do for Vulkan, claim 8 for
geometry stages, the maximum for fragment shaders, and the actual size
for compute.

Instead of lowering the subgroup size so early, wait until we have more
information. In particular, we're going to want different subgroup
sizes from different stages depending on the API. We also defer
lowering of subgroup masks because the ge/gt masks require the subgroup
size to generate a subgroup mask.

When a pipeline uses transform feedback, the driver fallbacks to
the legacy path because NGG support for streamout is a non-trivial
amount of work.
AMDVLK also uses the legacy path for streamout, while RadeonSI

The assign_extra_samplers() adds the needed extra samplers but they need
to be used in the nir_tex_instr.
Otherwise the plane information is simply lost and all nir_tex_instr use the
same sampler.
Here's an example of the bug:
NIR before st_nir_lower_tex_src_plane:
vec1 32 ssa_8 = load_const (0x00000000 /* 0.000000 */)
vec4 32 ssa_9 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord), ssa_8 (plane)
vec1 32 ssa_10 = load_const (0x00000001 /* 0.000000 */)
vec4 32 ssa_11 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord), ssa_10 (plane)
After:
vec4 32 ssa_9 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord)
vec4 32 ssa_11 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord)
