Not sure if this is actually required, but it matches previous behavior in NIR,
and some piglit tests expect this.
Notably GL-CTS does not need this, so maybe piglit is just broken.

INVALID_OPERATION is generated if pixel local storage is disabled and the
application attempts to issue a rendering command while a program object

INVALID_OPERATION is generated if pixel local storage is enabled and the

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.

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

This reverts commit 46bf687882.
We wont be removing this lowering file and having this workaround in
glsl_to_nir() creates a dependency on the const values that we could
otherwise avoid, so lets just move this back. Dropping the consts
will be useful in a follow up series that aims to drop all the glsl
ir function inlining code by converting builtin functions to nir.

glsl ir creates these temps to copy global initialiser values for
example. To avoid collisions during linking due to 2 shaders in the same
stage having temps with the same name we make sure to define these as
function variables not shader globals. This will put the temps into the
global instructions wrapper created in 7c5b21c032.

NIR doesn't really support global instructions such as global val
initilisation. So here we add functionality to glsl_to_nir() to
put these instructions into a temporary function that will be
later inlined into main.
We give the function a name starting with gl_mesa_tmp_ as functions
starting with gl_ are reserved and will not have any clashes with
user functions, we finish the name with the blake3 of the shader
source to avoid conflicts with multiple shaders attached to a single
stage.

Most of our visitors have custom destructors because they wrap C types,
and need to manually call destructors for those types. Because of this,
the implicitly generated copy constructors and copy-assignment operators
are not safe due copying pointers rather than data. Since we don't need
these features just delete them, so any attempt to use them would be a
compilation error. This doesn't fix any existing issue except stopping
coverity from complaining, but it does prevent new issues in the future.
