When dealing with a vertex input that takes multiple rows, the value of
nir_intrinsic_base points to a driver-location-based index, but we need
to emit a location-based index (or more specifically, an index that
increments once per input, not once per register). Add a mapping to
the module of base -> ID.

In order to get the semantics right, we need to know how many of the clip/
cull fields are designated for which purpose. In the case of a shader that
can receive these fields as both input and output, the shader_info property
is reserved to store the output info. We could add a dedicated input field
to shader_info, but since it'd probably only be useful for us, just send
it through a side channel during shader linking.

Docs say that its presence in signatures as a "shadow" element (meaning it's not
accessed via load/store, but with a dedicated opcode) is legacy. It seems it
wasn't carried forward when HS/DS were added in D3D11.

DXIL validation will complain if the tess factor signature entries have the

Note that this requires the shader info "tess" data to be correct.
For GLSL tess control shaders, only the output primitive count is
automatically available. The rest will need to be either guessed
or filled in from a matching tess eval (domain) shader. This is handled
by the d3d12 driver in a later patch.

The instruction and block lists are moved into a new "function definition"
struct, and the DXIL module tracks one at a time for adding instructions
into. The NIR side still only emits the main function here though.

The resource declarations are module-wide, but the resource handles
are function-local. A future change will add multi-function support,
but requires these handles to be potentially emitted multiple times.
The alloca used for scratch is also function-local.
This is the same pattern that the DXBC to DXIL converter uses.

DXIL adds this in SM6.6, so when we get around to being able to
emit SM6.6, we can conditionally turn this off and support emitting
the new intrinsic. Until then, this is easy.

This *almost* matches what GLSL wants, except for the handling of
large widths. You can see this in the lowering algorithm:
(('bitfield_insert', 'base', 'insert', 'offset', 'bits'),
('bcsel', ('ult', 31, 'bits'), 'insert',
('bfi', ('bfm', 'bits', 'offset'), 'insert', 'base')),
'options->lower_bitfield_insert'),
DXIL's 'bfi' instruction is an inseparable pairing of NIR's 'bfi(bfm(...), ...)',
so we just apply the additional bcsel in the backend.
