6ad88a8f08 spirv: Support SPV_KHR_subgroup_uniform_control_flow
There's no SPIR-V Capability associated, so check in the Execution
Mode.  For now, don't keep track of whether a shader uses uniform
control flow in the shader_info, we can add that when/if a driver
actually need that information.

786fa3435c spirv_to_nir: Add environment variable to change default log level
During dEQP runs for radv, I see a lot of warnings like,

ERROR - dEQP error: SPIR-V WARNING:
ERROR - dEQP error:     In file ../src/compiler/spirv/spirv_to_nir.c:1073
ERROR - dEQP error:     Decoration not allowed on struct members: SpvDecorationRestrict
ERROR - dEQP error:     408 bytes into the SPIR-V binary

This fails jobs on Gitlab, due to,

Job's log exceeded limit of 4194304 bytes.
Job execution will continue but no more output will be collected.

Since it doesn't seem feasible right now to fix the many shaders in
the VK-CTS triggering this warning, add an environment toggle that
allows test runners to only see the level of commentary they want.

v2 from Martin:
 - Add my SoB

v3 from Martin:
 - fix the indentation (suggested by Eric)
 - put the declarations at the top of the function

v4 from Martin:
 - make vtn_default_log_level() static (Marcin)
 - cache the default level in vtn_log (Marcin)
 - move vtn_log_level_strings inside vtn_default_log_level()
 - Fix the build issue on MSC

64cb143b92 spirv: Fix handling of OpBranchConditional with same THEN and ELSE
When an OpBranchConditional that had two equal branches was parsed, we
were treating it as a regular OpBranch.  However this doesn't work
well when there's an associated OpSelectionMerge.  We ended up
skipping marking the merge block as such, and depending on what was
inside the construct we would end up trying to process the block
twice.

Fix this by keeping the vtn_if around, but when emitting NIR identify
the two equal branch case.

This also removes a subtle issue in spirv_to_nir:
info.cs.shared_memory_explicit_layout was used without checking for

also depended on presence of shared variables.

e763db4a47 spirv: Don't replicate patch bool in vtn_variable
When we originally added patch variable handling to spirv_to_nir, we
were splitting I/O block variables in spirv_to_nir, so we weren't
guaranteed to have a nir_variable early enough in processing.

Since b0c643d8f5 ("spirv: Use NIR per-member splitting"), we've been
using NIR per-member splitting where we have a nir_variable which has
a separate nir_variable_data per member.  With this, we can drop
vtn_variable::patch and use the patch boolean on the nir_variable
instead.

ed20e69b0c vtn: Handle ZeroExtend/SignExtend image operands
These decorations allow you to override the signedness of image
instructions. This means that we have to override the type we get from
the sampled image.

Apparently both Intel and AMD get the type from the descriptor rather
than the instruction, but this appears to not be the case with Adreno,
which is why this wasn't noticed until now. So this probably won't fix
any preexisting bugs, but it's required to fix
dEQP-VK.image.extend_operands_spirv1p4.* when exposing VK_KHR_spirv_1_4
on turnip.

Running spirv_to_nir on the SPIR-V sample above and for the geometry
entry point would say that (among others):

By removing any reference to `%gl_WorkGroupSize`, the output would
change to (among others):

* vertices out: 4
* input primitive: POINTS
* output primitive: TRIANGLE_STRIP

* Move the check from inside `handle_workgroup_size_decoration_cb()` to
  its caller (Caio Marcelo de Oliveira Filho )
* Add an assert on the shader stage before using
  `workgroup_size_builtin` (Caio Marcelo de Oliveira Filho )

0c3fe06421 spirv: Skip creating unused variables in SPIR-V >= 1.4
Newer versions of SPIR-V require that all the global variables used by
the entry point are declared (in contrast to only I/O in previous
versions), so there's no need to remove dead variables or keep track
of the indirectly used variables.

e3abbe7a24 spirv: Count variables *after* unused ones are removed
Previous code was counting more variables than those used by the entry
point.

cc98ba2eaf spirv: Use OpEntryPoint to identify valid I/O variables
OpEntryPoint declares the list of variables in Input and Output
storage classes that are used.  Use that information to skip creating
other variables from such storage classes that are unused by the entry
point.

After that change, is not necessary to use remove dead variables for
those types of variables; and because of that is also not necessary to
lower initalizers for output variables.

a0d73ca65c spirv: Don't remove dead variables in create_library mode
The issues fixed by the removal happen when a module has multiple
entry points and conflicting global variables.  Neither conditions are
expected in a library.

currently they are also counting all the images / textures in the
module instead of in the shader (entrypoint).
