The combined sampler is created as a SAMPLER instead of a TEXTURE
because that fits all our current infrastructure. The only problem is
that in the CTAB it must appear as a Texture, so the new field
hlsl_type.is_combined_sampler is added.

Looking at the implementation of shader_sm4_read_dcl_sampler(), vsir
stores the resource index range both in
vkd3d_shader_instruction.declaration.sampler.range
and in the
vkd3d_shader_instruction.declaration.sampler.src.reg.idx[1-2]
indexes, so we do the same.
It is also worth noting that for shader models lower than 5.1, vsir
has a normalization on the ins->declaration src register indexes.
Refer to the following comment:
/* SM5.1 places a symbol identifier in idx[0] and moves
* other values up one slot. Normalize to SM5.1. */
on shader_sm4_read_param().
This normalization is also added to the generated vsir instructions.
Translate the instructions that contain hlsl_blocks. Also move
other control flow instructions such as HS_CONTROL_POINT_PHASE and
RET to the vsir_program so that we can directly iterate over it now.
These system values are bound to the same allocation rules as other
semantics: they can share registers with other semantics with the same
interpolation mode and they prefer forming shorter writemasks. However,
for some reason, these don't allow further semantics to share the same
register once allocated, except among themselves.
