The GLSL to NIR compiler supports the LowerTessLevel flag to convert
gl_TessLevelInner/Outer from their GLSL declarations as arrays of
floats to vec4/vec2s to better match how they are represented in

This commit adds the similar support to the SPIR-V to NIR compiler so
turnip can use the same IR3/NIR tess lowering passes as freedreno.

This commit adds a tess_levels_are_sysvals flag to
spirv_to_nir_options similar to GLSLTessLevelsAsInputs in the GLSL to

TessLevelOuter in the DS as sysvals.

When we originally wrote spirv_to_nir we didn't have a good scalar value

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.

ARB_gl_spirv adds the ability to use SPIR-V binaries, and a new

From OpenGL 4.6 spec, section 7.2.1"
"Shader Specialization", error table:
INVALID_VALUE is generated if <pEntryPoint> does not name a valid
entry point for <shader>.
INVALID_VALUE is generated if any element of <pConstantIndex>
refers to a specialization constant that does not exist in the
shader module contained in <shader>.""
v2: rebase update (spirv_to_nir options added, changes on the warning
logging, and others)
v3: include passing options on common initialization, doesn't call
setjmp on common_initialization
v4: (after Jason comments):
* Rename common_initialization to vtn_builder_create
* Move validation method and their helpers to own source file.
* Create own handle_constant_decoration_cb instead of reuse existing one
v5: put vtn_build_create refactoring to their own patch (Jason)
v6: update after vtn_builder_create method renamed, add explanatory
comment, tweak existing comment and commit message (Timothy)
So now, during spirv_to_nir, it uses the capability instead of the
extension. Note that we are really doing here is treating
SPV_AMD_gcn_shader as other supported extensions. SPV_AMD_gcn_shader
is not the first SPV extension supported. For example, the capability
draw_parameters infers if the extension SPV_KHR_shader_draw_parameters
is supported or not.
This could be seen as counter-intuitive, and that it would be easier
to define which extensions are supported, and based our checks on
that, but we need to take into account that some capabilities are
optional from core, and others came from new extensions.
Also this commit would make the implementation of ARB_spirv_extensions
easier.

Before, we always left workgroup variables as shared nir_variables and
let the driver call nir_lower_io. This adds an option to do the
lowering directly in spirv_to_nir. To do this, we implicitly assign the
variables a std430 layout and then treat them like a UBO or SSBO and
immediately lower all the way to an offset.
As a side-effect, the spirv_to_nir pass now handles variable pointers
for workgroup variables.

OpLine.
2) There is now a logging callback mechanism so that errors can get
