Make sure that both per-vertex and per-primitive attribute
ring stores are finished before position or primitive export
instructions are executed.
This is necessary because we need to ensure that mesh shader
waves work correctly when they have either vertex-only or
primitive-only waves.

Cleanup the code that generates the two channels of the
primitive export instruction, and move storing the built-in
per-primitive outputs out to match how vertex attributes work.
Prepares the mesh shader lowering for a workaround that
affect export instructions.

This is a HW bug workaround for some (all?) GFX11 chips.
On these chips, rasterization can start before the attribute ring
stores are finished, which can cause issues.
As a workaround, wait for attribute ring stores to finish
before doing the position export.
Mesh shaders will be taken care of in another commit.

Prepares for a workaround. Makes it possible for this function
to not emit the pos0 export at all so that it can be emitted
by a subsequent call to the function later.

This prepares for a workaround where we won't need to add
the done flag to the last export in this function, because
it will be added in a subsequent call to the same function.

For z surfaces, flags.texture should be based on
RADEON_SURF_TC_COMPATIBLE_HTILE alone. Otherwise, addrlib could pick a
_X/_T swizzle mode for a MSAA depth texture, which is said to be broken:
When _X/_T swizzle mode was used for MSAA depth texture, TC will get zplane
equation from wrong address within memory range a tile covered and use the
garbage data for compressed Z reading which finally leads to corruption.

The nir_op_is_vec() helper I added in 842338e2f0 ("nir: Add a
nir_op_is_vec helper") treats nir_op_mov as a vec even though the
semanitcs of the two are different. In retrospect, this was a mistake
as the previous three fixup commits show. This commit splits the helper
into two: nir_op_is_vec() and nir_op_is_vec_or_mov() and uses the
appropriate helper at each call site. Hopefully, this rename will
encurage any future users of these helpers to think about nir_op_mov as
separate from nir_op_vecN and we can avoid these bugs.

The names basically had the same meaning. Changing them to
uniform_shader_addr and shader_addr makes it clear, that
uniform_shader_addr is the jump target and shader_addr is the next
shader executed by this invocation.
The next_ prefix is dropped since both are input and output variables.

Instead, we replace it directly with nir_def. We could replace it with
nir_dest but the next commit gets rid of that so this avoids unnecessary
churn. Most of this commit was generated by sed:
sed -i -e 's/dest.dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
There were a few manual fixups required in the nir_legacy.c and
nir_from_ssa.c as nir_legacy_reg and nir_parallel_copy_entry both have a
similar pattern.
