Setting variable names currently always uses ralloc, but the new
nir_variable_* helpers will mostly eliminate ralloc/malloc in a later
commit.
This just updates all places that touch nir_variable names to use the new
helpers.

These are not necessary and can be expensive. I think they were added
because of a misunderstanding of the informative descriptions in the
Vulkan memory model, or because the memory model requires make
visible/available barriers to have these semantics.
Because we use these to implement MakePointerVisible/MakePointerAvailable,
we can skip that requirement in NIR.

From Vulkan 1.4.321 spec:
The implicit availability operation is program-ordered between the barrier
or atomic and all other operations program-ordered before the barrier or
atomic.
...
The implicit visibility operation is program-ordered between the barrier
or atomic and all other operations program-ordered after the barrier or
atomic.

Backends probably already deal with this, but these would be needed to
prevent NIR passes from moving accesses outside the critical section.

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
done && \
sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

The untyped pointer types only have a storage class associated, and the
operations using them would carry the necessary "data type" information.
Untyped pointers themselves are identified by "vtn_type::pointed" being
NULL. For the NIR lowering the operations will have explicit casts
before them when applicable and the nir_derefs representing untyped
pointers will use the "void" glsl_type.

There are a few things that could cause us to return NULL here and we
should just fail to parse the SPIR-V if that ever happens instead of
crashing when someone tries to access it.

This adds a vtn_pointer_ssa_is_desc_index() helper and makes both
to/from_ssa work in terms of it, ensuring we never screw up the

These haven't existed in a while but the vtn_pointer fields stayed
around. Drop offset since no one uses it and rename block_index to
desc_idx with a better comment.

Similar to nir_lower_alu_width(), the callback can return the
desired number of components for a phi, or 0 for no lowering.
The previous behavior of nir_lower_phis_to_scalar() with lower_all=true
can be elicited via nir_lower_all_phis_to_scalar() while the previous
behavior with lower_all=false now corresponds to nir_lower_phis_to_scalar()
with NULL callback.

The spirv-to-c-array.py script assembles a SPIR-V module,
then disassembles it, capturing that text, then re-assembles
that text, providing it on stdin. But this last invocation of
spirv-as must use '-' to specify that the text input appears
on stdin.
Currently it always errors out, complaining that there must
be exactly one input file.
