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.

If the shader has multiple payload variables, split passes might not
preserve the order and this can cause the offsets used for the stores to
not match the payload offsets for nir_intrinsic_trace_ray.

When multiview is used and the FS is compiled separately with GPL, the
view index still needs to be lowered, otherwise it's crashing later.
The lowering doesn't need to know the previous stage because ViewIndex
is a global thing (ie. it's neither a per-vertex or a per-primitive
varying).

Some NIR passes (such as nir_opt_varyings) rely on having the
XFB info in explicit I/O intrinsics. If we want to use those,
we need to add this info.

When there are no VS outputs, we expect that the drivers set
the LS-HS vertex stride to zero, which will produce the
same result as no_inputs_in_lds did.
Remove the unnecessary code path from the output lowering.

Right now we don't allocate LDS for HS inputs when all HS inputs are passed
via VGPRs.
This changes it to skip allocating exactly the HS inputs passed via VGPRs
by reducing the inputs_read mask to remove holes.
radeonsi changes to the LDS allocation will be in a different MR.

This pass uses constant folding to determine which invocation is read by shuffle
for each invocation. Then, it detects patterns in the result and uses more
a specialized intrinsic if possible.
For booleans it creates inverse_ballot.

The goal of this patch is to make the TCS->TES shader I/O
independent of assigned I/O driver locations.
Always using the unlinked approach means a larger stride when
calculating some memory addresses, but otherwise should have no
perf impact whatsoever, because this only affects how TCS
outputs are stored to VRAM, and doesn't affect how they are
stored in LDS.

This commit does two things at once, which cannot be split
into two commits because otherwise the driver would regress
in-between the two.
Change radv_nir_shader_info_pass so that it uses I/O intrinsics
instead of I/O variables for determining FS information.
Also eliminate gaps between input slots caused by unused input
variables. To this end, we use nir_recompute_io_bases after
nir_lower_io instead of assigning driver locations before it.
As part of this, we can now omit a clip/cull input when only
the second one is used.
