Sufficient for compiling a no-op pixel shader.
This should probably be rebased on top of !263 because it introduces vkd3d_spirv_get_type_id_for_data_type(), which 263 renders unnecessary.
!263 is not essential, but I think using two different type systems in the backend is not ideal.
-- v3: vkd3d-shader/dxil: Emit undefined constants. vkd3d-shader/spirv: Introduce an undefined register type. vkd3d-shader/dxil: Emit the shader instructions. vkd3d-shader/spirv: Do not normalise Shader Model 6 shaders.

What are we trying to do here, exactly?
Yes it is for tests added later. I've deleted it from this series. We will need a means to add the signature for the tests.
For the d3d12 and shader runner tests I've been using an environment variable to specify the path to DXC, HLSL source declarations in d3d12.c, and an `[enable]` directive in shader runner. Are those acceptable for upstream?

It's of course not ideal to depend on DXC/dxcompiler for the DXIL shader runner tests like that, but I think we can work with that, yes. There's some precedent as well, because we can also use d3dcompiler for running shader runner tests.
In terms of the checksum, the most practical way to make that work in the shader runner is probably to introduce a flag like "VKD3D_SHADER_PARSE_DXBC_IGNORE_CHECKSUM" for vkd3d_shader_parse_dxbc(), then use that to parse the DXBCs produced by Linux DXC, and use vkd3d_shader_serialize_dxbc() to create a DXBC blob to pass to d3d12/vkd3d. Also, would we need to use DXC, or could we use the dxcompiler library?
