If this is reverted on top of "Lower numeric casts", then the shader
runner crashes with:
shader_runner: ../vkd3d/libs/vkd3d-shader/vkd3d_shader_private.h:1165: vkd3d_write_mask_component_count: Assertion `1 <= count && count <= VKD3D_VEC4_SIZE' failed.
While the HLSL copiler is expected to output correct programs, the DXBC
parser should not crash on malformed inputs anyway, so there is a bug
to be fixed there too.
v2:
* Use hlsl_type_component_count()
