I think this was broken as there might be a store_output with
less than 4 components to a location that shouldn't be smoothed
anyway (i.e. not the first one).
nir_lower_poly_line_smooth now handles the case where the first location
doesn't have 4 components.

This fixes depth-only rendering with mesh shaders,
as well as array derefs in unlinked shaders in general.
Lowering array derefs of vectors is necessary for correctness.
Without this, nir_lower_io will incorrectly add the array index
to the IO intrinsic base instead of to the component offset.
This was previously only done during shader linking, which leaves
some problems with unlinked shaders and depth-only rendering.
Whether these calls can be safely removed from shader linking
will be investigated in a future commit.

Determine whether the device has hardware raytracing support early, and
then use this result where needed, instead of checking for `gfx_level`
every time.
This is a prerequisite for CYAN_SKILLFISH chip enablement. This chip is
still GFX10, not GFX10_3, but has hardware support for accelerated
`image_bvh{,64}_intersect_ray` instructions. Just checking for `gfx_level`
is insufficient for it.

No need to open-code this one now that we have a generic helper.

Cross-invocation TCS input access doesn't prevent same-invocation access.
This improves shaders that use both for the same inputs.
Also, if some components of a vec4 slot only use same-invocation access and
other components only use cross-invocation access (it's possible after
compaction), this takes the VGPR path for the components with
same-invocation access, which didn't happen previously because all masks
only describe whole vec4s.

It's allowed to place OpExecuteCallableKHR in a SPIR-V, even if the RT
pipeline doesn't contain any callable shaders. Unreal hits this case and
crashes. We can assume the intrinsic never gets executed, so we can
simply remove it.

We want to make the implicit VS primitive ID a per-primitive
output attribute, which means that this has to be last.

Use box with largest ray interval for shadow rays (terminate on first
hit) as it maximizes the probability of finding some object in that box;
for reflection (closest hit) rays, use midpoint instead, which defers
processing of larger boxes the ray origin is in in favor of smaller
boxes closer to origin.
Since the sorting mode must be uniform, when terminate_on_first_hit flag
is divergent, we leave it as closest.

There are some FS built-ins that can be per-vertex or
per-primitive depending on whether a mesh shader is used:
primitive ID (implicit in VS), layer and viewport.
However, the HW requires per-primitive FS inputs to be ordered last.
This causes bugs when the same unlinked FS is used together
with VS/TES/GS and MS (with unlinked ESO or fast-linked GPL).
To solve this problem, we reorder the FS inputs so that these
potentially per-primitive inputs go after per-vertex inputs but
before per-primitive inputs.

This will need to be set to true when the GLSL linker lowers IO, which
can later be unlowered by st/mesa, and then drivers can lower it again
without load_interpolated_input. Therefore, it can't be a global
immutable option.

If nir_tcs_info::all_invocations_define_tess_levels is true, the pass
doesn't have to insert a barrier and use output loads to get tess level
output values. It can just use the SSA defs that are being stored (or phis
thereof) to get the tess level output values.
The remaining tcs_info fields will be used by the HS shader message.
