2fbce4c9e1 nir/spirv: Use the correct sources for CompareExchange on images
The CompareExchange operation has two "Memory Semantics" parameters instead
of one so the real arguments start at w[7] instead of w[6].

ab6126bb1d nir/spirv: Swap the argument order for AtomicCompareExchange
SPIR-V has the two arguments in the opposite order from GLSL.  NIR uses the
GLSL order so we had them backwards.

Fixes dEQP-VK.spirv_assembly.instruction.compute.opatomic.compex

0aae486a8b nir/spirv: Don't multiply the push constant block size by 4
I have no idea why we were multiplying by 4 before.  The offsets we get
from SPIR-V are in bytes and so is nir->num_uniforms so there's no need to
do any adjustment whatsoever.

b2fe134064 spirv: Use the system value version of gl_FrontFace
SPIR-V treats it as an input but NIR wants the system value.  This
shouldn't have been too much of a surprise given that we have to do the
same conversion in the GLSL IR to NIR pass.

6eb39fa255 nir/spirv: Complete the list of capabilities
Previously we supported a subset of capabilities and just left a default
case for the others.  It's time to stop being lazy and actually audit the
capabilities.  This should bring them up-to-date with reality.

9f9f229359 nir/spirv: Allow pointless variable decorations on inputs
SPIR-V specifies that a bunch of stuff gets applied to types.  This means
taht a local variable could get, for instance, an array stride.  Just
because it's pointless doesn't mean you'll never see it.

961369d597 nir/spirv: Add explicit handling for all decorations
From time to time we have had cases where glslang has added a decoration we
don't handle and it has caused problems.  This audit ensures that, for
every decoration, we either handle it or hit an unreachable() with an
accurate description of why we don't have to.

de45da6a8c spirv: Handle the PixelCenterInteger execution mode.
This isn't allowed by Vulkan, but might be useful someday for
SPIR-V in OpenGL (if that ever becomes a thing).  It's easy enough
to hook up, and as precedent, we already do so for OriginLowerLeft.

b1e6d069da spirv: Properly size the src[] array.
Operations like nir_op_bitfield_insert have four arguments, and Coverity
isn't privy to the fact that 4-argument operations aren't possible here,
so it thinks this can lead to memory corruption. Just increase the size
of the array to quell any fears.

742bc53d04 spirv: Fix structure splitting with per-vertex interface arrays.
We want to use interface_type, not vtn_var->type.  They're normally
equivalent, but for geometry/tessellation per-vertex interface arrays,
we need to unwrap a level.

Otherwise, we tried to iterate a structure members but instead used
an array length.  If the array length was longer than the number of
fields in the structure, we'd crash.

Fixes the CreatePipelineGeometryInputBlockPositive layer validation
test.

v2: Just use glsl_without_array() on the vtn_var type
    (requested by Jason Ekstrand).
