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.

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.

This seems valid per the SPIR-V spec to use OpSampledImage with
OpUndef instead of OpTypeImage or OpTypeSampler. When the image
operand is undefined, SPIRV->NIR emits an undef instruction that
can be removed later by the compiler.
This fixes shader compilation crashes with Red Dead Redemption II.

SPIRV OpControlBarrier can have both a memory and a control barrier
which some hardware can handle with a single instruction. Let's
turn the scoped_memory_barrier into a scoped barrier which can embed
both barrier types. Note that control-only or memory-only barriers can
be supported through this new intrinsic by passing NIR_SCOPE_NONE to the
unused barrier type.

We use vtn_vector_extract to handle vector component level derefs. This
makes us gracefully handle the case where your vector component is OOB
and give you an undef. The SPIR-V working group is still working out
whether or not this is technically legal but it's very little code for
us to handle it so we may as well.

Because the types etc. are required to logically match, we can just
copy-propagate the guts of the vtn_value. This was causing issues with
some new CTS tests that are doing an OpCopyObject of a sampler which is
a special-cased type in spirv_to_nir. Of course, this is only a partial
solution. Ideally, we've got a bit of work to do to make all the
composite stuff able to handle all types including images, sampler, and
combined image/samplers but this gets some CTS tests passing.
