47ebb50cab spirv: Hand-roll fewer vtn_ssa_value creations
Previously, we created our vtn_ssa_value in _vtn_variable_load_store
manually as we did the recursive load/store.  Instead, we now create the
SSA value before calling into the recursive function.  This is a tiny
bit less efficient but it removes a case of hand-rolling vtn_ssa_value
creation.  For symmetry, we make _vtn_block_load_store assume the value
is already created.  Finally, we remove a trivial hand-rolled case in
vtn_composite_extract.

085ade4125 spirv: Simplify vtn_ssa_value creation
For three different functions which create vtn_ssa_values, we had three
completely different implementations.  This unifies them all to roughly
the same algorithm.  While we're at it, we take advantage of the
nir_build_imm helper to avoid some extra code in vtn_const_ssa_value.

ea246c3950 spirv/subgroups: Stop incrementing w
The w++ is to handle a differences between the KHR extension and Vulkan
1.1 feature where the Vulkan 1.1 instructions take an scope parameter.
While incrementing w technically works, it's really subtle and very easy
to miss when reading the code.

8dfee57bdc spirv: Clean up OpSignBitSet
For some reason, we were doing a signed shift vectors and an unsigned

difference whatsoever.  The fact that we're doing different things for
vectors vs. scalars is bonkers.  Let's simplify the code a bit.

af81486a8c spirv: Simplify our handling of NonUniform
The original implementation of SPV_EXT_descriptor_indexing was extremely
paranoid about the NonUniform qualifier, trying to fetch it from every
possible location and propagate it through access chains etc.  However,
the Vulkan spec is quite nice to us on this and has very strict rules
for where the NonUniform decoration has to be placed.  For image and
texture operations, we can search for the decoration on the spot when we
process the image or texture op.  For pointers, we continue putting it
on the pointer but we don't bother trying to do anything silly like
propagate it through casts.

 block block_4:

After block_3 extraction and reinsertion, phi->pred becomes invalid

de0ebaf09d nir/algebraic: optimize bcsel(a, 0, 1) to b2i
This avoids combination with other bcsel operations,
and as b2i is often a no-op (when used for iadd and such),
the resulting pattern is preferable.

fac813dc61 spirv: don't split memory barriers
If the SPIR-V had a shared+image memory barrier, we would emit two NIR
barriers: a shared barrier and an image barrier.

Unlike a single barrier, two barriers allows transformations such as:

intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1)
intrinsic memory_barrier_shared () ()
intrinsic memory_barrier_image () ()
intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0)
->
intrinsic memory_barrier_shared () ()
intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0)
intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1)
intrinsic memory_barrier_image () ()

This commit fixes two dEQP-VK.memory_model.* CTS tests with ACO.
