Crysis 2 and 3 Remastered's RT shaders non-uniformly index into SSBO
descriptor arrays without specifying the NonUniformEXT qualifier on the
relevant access chains/load ops. This leads to artifacts around objects.
To add insult to injury, the game fails to provide a meaningful
applicationName/engineName in the Vulkan part of the DX11-Vulkan interop
solution used for RT. Both of these fields are set to "nvpro-sample"
(perhaps the code has been copied from NVIDIA's sample applications).
Therefore, fall back to executable name matching.

This new entrypoint takes in a SPIR-V blob and generates a header containing
a static inline nir_builder-family function for each function in the SPIR-V
library. The generated function will look for the function in the shader and, if
not found, insert a new nir_function with the appropriate signature -- to be
linked with the library later. Then, it will call the function, with the
appropriate gymnastics to handle return values as necessary.
This makes it super convenient to wrap CL libraries for use in a NIR pass.

When running in the CI environment, instead of crashing the test
binary, it is preferable to just fail gracefully (in this case return
a NULL shader) like is done in release mode, so other tests continue
to be executed.
For convenience add a variable break_on_failure to the test so the
breaking behavior can be re-enable in individual tests when debugging.

During dEQP runs for radv, I see a lot of warnings like,

ERROR - dEQP error: Decoration not allowed on struct members: SpvDecorationRestrict

Since it doesn't seem feasible right now to fix the many shaders in

The GLSL to NIR compiler supports the LowerTessLevel flag to convert

This commit adds a tess_levels_are_sysvals flag to

TessLevelOuter in the DS as sysvals.

union to handily use so we rolled our own thing for spec constants. Now
that we have nir_const_value, we can use that and simplify a bunch of

The caller is responsible for setting up the ubo_addr_format value as
contrary to shared and global, it's not controlled by the spirv.
Right now clovers implementation of CL constant memory uses a 24/8 bit format
to encode the buffer index and offset, but that code is dead as all backends
treat constants as global memory to workaround annoying issues within OpenCL.
Maybe that will change, maybe not. But just in case somebody wants to look at
it, add a toggle for this inside vtn.

On AMD, FragCoord should be a sysval because it is handled separately
from all the other inputs. We were already doing this in radeonsi, but
we weren't doing it with radv. It'll be much more annoying to handle
VARYING_SLOT_POS in fragment shaders when we let NIR lower FS inputs for
us, so here we add an option so that radv can get it as a system value.

spirv_to_nir() returned the nir_function corresponding to the
entrypoint, as a way to identify it. There's now a bool is_entrypoint
in nir_function and also a helper function to get the entry_point from
a nir_shader.
The return type reflects better what the function name suggests. It
also helps drivers avoid the mistake of reusing internal shader
references after running NIR_PASS on it. When using NIR_TEST_CLONE or
NIR_TEST_SERIALIZE, those would be invalidated right in the first pass
executed.
