With descriptor heap the driver will also have to emit indirect
descriptor heaps in some cases.
Rename couple of things to make them more generic.

Lowering them earlier right after VTN would allow us to implement
embedded samplers for descriptor heap properly for merged shaders.
Non-immediate samplers are still lowered in
radv_nir_apply_pipeline_layout because they require shader arguments.

This means we can actually implement varying subgroup size correctly.
It also means that we implement the implicit SPIR-V 1.6 full subgroups
requirement in compute shaders with cswave32/rtwave32.
In the future it will also allow more optimizations that use the subgroup size.

The only somewhat complex case here is GFX10 geometry shaders, if gewave32 is
used. We then only know the subgroup size when is_ngg is decided, as legacy
GS doesn't support wave32.

All shaders are allocated in the 32-bit addr space. To avoid an issue
with alignment, and also for future work, there is an unused user SGPR.

This has been annoying me for quite some while, the level of indention
makes reviewing code changes in Gitlab harder.
I think now is a good time to change this before more cmat lowering is added.

Most of the time with nir_def_rewrite_uses_after, you want to rewrite after the
replacement. Make that the default thing to be more ergonomic and to drop
parent_instr uses.
We leave nir_def_rewrite_uses_after_instr defined if you really want the old
signature with an arbitrary after point.

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

for intrinsics, we have these really nice builders using designated initializers
+ macros to specify optional indices. texture instrs have even more craziness
involved, but we can do the same trick. this commit takes the existing "fixed
form" deref-centric tex builders and generalizes them to work with non-deref
textures, making it useful also for GL and late VK passes, while providing an
API that strives to be ergonomic and consistent.
this series only implements a subset of possible texture operations for now, but
more generalizing could be added as people have need.
