That program is only meant to be used in the specific context of the CI,
so we don't care about querying the terminal or honouring environment
variables.
The swizzle from vsir_swizzle_from_writemask() is for use with a
contiguous write mask starting at bit zero, but we need the final write
mask to match that of the original MAD instruction.

This was the original intention, but it didn't happen because of a bug:
what we need to know at this point is whether the push descriptor set is
being used in general (which is tracked by the corresponding Vulkan
extension bit), not whether the descriptors we're currently processing
are to be put in the push descriptor set (which is tracked by
`push_descriptor'). Indeed, `push_descriptor' is always false when
processing static samplers, precisely because we want to segregate them
in different sets.
This fixes a rendering bug in "The Dark Pictures Anthology: Man of
Medan".

For example, a HLSL shader like this:
tbuffer t0
{
float4 data;
};
float4 main() : sv_target
{
return data;
}
would be compiled to the following:
ps_4_0
dcl_resource_buffer (mixed,mixed,mixed,mixed) t0
dcl_output o0.xyzw
dcl_temps 1
ld r0.xyzw, l(0, 0, 0, 0), t0.xyzw
mov o0.xyzw, r0.xyzw
ret
VSIR_DATA_MIXED used to be mapped to VKD3D_SHADER_COMPONENT_UINT by
vkd3d_component_type_from_data_type(), but we no longer use that.
