This will be necessary once we start compiling multiple variants due to
different const size limits, and it will also be necessary for properly

The app is allowed to never bind descriptor sets that are statically
unused by the pipeline, which would've caused a context fault since
CP_LOAD_STATE6 would try to load the descriptors that don't exist. Fix
this by not preloading descriptors from unused descriptor sets. We could
do more fine-grained accounting of which descriptors are used, but this
is enough to fix the problem.

This commit fixes a GS regression introduced in !4562 where
ir3's GS lowering pass was moved from common code (ir3_nir) to
freedreno-specific code (ir3_shader). For GS support in turnip, we
need to add the GS lowering pass back in, this time in tu_shader.
As for the nir_gather_info change, the GS lowering pass has always
introduced a discard_if intrinsic into the GS. Previously, we simply
ran nir_shader_gather_info before GS lowering, but now since we lower
the GS before we need to remove the assertion that only a FS can use
the discard_if intrinsic.

Apparently this is allowed, and the CTS started doing this more often
recently which resulted in frequent hangs running the entire CTS. I

When we originally wrote spirv_to_nir we didn't have a good scalar value
union to handily use so we rolled our own thing for spec constants. Now
that we have nir_const_value, we can use that and simplify a bunch of
the spec constant logic.

Under the bindless model, there are 5 "base" registers programmed with a
64-bit address, and sam/ldib/ldc and so on each specify a base register
and an offset, in units of 16 dwords. The base registers correspond to
descriptor sets in Vulkan. We allocate a buffer at descriptor set
creation time, hopefully outside the main rendering loop, and then
switching descriptor sets is just a matter of programming the base
registers differently. Note, however, that some kinds of descriptors
need to be patched at command recording time, in particular dynamic
UBO's and SSBO's, which need to be patched at CmdBindDescriptorSets
time, and input attachments which need to be patched at draw time based
on the the pipeline that's bound. We reserve the fifth base register
(which seems to be unused by the blob driver) for these, creating a
descriptor set on-the-fly and combining all the dynamic descriptors from
all the different descriptor sets. This way, we never have to copy the
rest of the descriptor set at draw time like the blob seems to do. I
mostly chose to do this because the infrastructure was already there in
the form of dynamic_descriptors, and other drivers (at least radv) don't
cheat either when implementing this.

Carve out some space at the beginning for push constants, and push them
directly, rather than remapping them to a UBO and then relying on the
UBO pushing code. Remapping to a UBO is easy now, where there's a single
table of UBO's, but with the bindless model it'll be a lot harder. I
haven't removed all the code to move the remaining UBO's over by 1,
though, because it's going to all get rewritten with bindless anyways.

The ir3 compiler only lowers the VS and GS for geometry shading if
the corresponding has_gs key is set in the shader key. Without it,
GS-specific intrinsics like load_per_vertex_input won't get lowered
and the GS header will be initialized with invalid values.

- Add one member to the existed ir3_stream_output so that we could
assign location information from nir_xfb_info, rather than defining
new struct.
- Redefine maximum of so buffers, streams and outputs, which will be
used for turnip.
- Also enable caps for transform feedback for spirv_to_nir.
v2. Remove redefined maximums and use IR3_MAX_SO_* and add
IR3_MAX_SO_STREAMS.
v3. Remove the newly added location field so that we could keep aligned
with 32 bytes. Instead we create an array mapping between the location
and consecutive index, which is GL driver is doing.

So far this doesn't handle the texture state-based storage image access
loads, and doesn't support descriptor arrays (same as SSBOs). The texture
side is more tricky, since we have another remapping table to work around.

Just make it be all SSBOs then all storage images. The remapping table
was there to make it so that the big gap present from gallium's atomic
lowering would get cleaned up, but that's no longer case. The table has
made it very hard to support Vulkan storage images, so it's time for it to
go.
This does mean that an SSBO/IBO that is only loaded (or size-queried) will
now occupy a slot in the table where it wouldn't before. This seems like
a minor cost compared to being able to drop this much logic.
With the remapping table gone, SSBO array handling for turnip just falls
out.

spirv_to_nir() returned the nir_function corresponding to the
entrypoint, as a way to identify it. There's now a bool is_entrypoint
in nir_function and also a helper function to get the entry_point from
a nir_shader.
The return type reflects better what the function name suggests. It
also helps drivers avoid the mistake of reusing internal shader
references after running NIR_PASS on it. When using NIR_TEST_CLONE or
NIR_TEST_SERIALIZE, those would be invalidated right in the first pass
executed.

For a6xx, we construct/emit a single VS const state used for both
binning pass and draw pass. So far we were mostly getting lucky that
there were not (obvious) mismatches between the const_state (like
different lowered immediates) between the binning and draw pass
VS ir3_shader_variant.
And I guess this situation will come up more as GS and tess is added
into the equation.
Since really everything about the const state is not specific to the
variant, move this. The main exception is lowered immediates, but these
are the last to appear in the layout, and it doesn't hurt for each new
shader variant to just append any immed's it lowers to the end of the
immediate state.
