ddf2aa3a4d build: avoid redefining unreachable() which is standard in C23
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

6b34e2174e nir: introduce ergonomic tex builder
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.

60a20bcf3d nir: Stop using instructions for debug info
Annotating ssa defs without affecting compilation is impossible with
debug info instructions since referencing a nir_def from the debug info
instr will add uses.

The old approach also stops worrking if passes reorder instructions.

This patch proposes a solution which should not regress performance just
like the old approach. The difference is that this one allocates a bit
more space for debug info instead of adding a new instruction for it.

666647acae nir: track some float controls bits per instruction
With float_controls2, shaders can decide on the behavior of
NaN/Inf/SignedZero preservation by decorating specific instructions, on
top of having a default for the whole program.
Add where to track these to nir_alu_instr and propagate them to new
instructions everywhere that exact is being done already.

a782809f81 nir/builder: Correctly handle decl_reg or undef as the first instruction
These are both handled by inserting them directly at the top of the
nir_function_impl.  However, if the cursor is already at the top, it
never gets updated so we end up inserting other stuff after the newly
inserted undef or decl_reg.  It's an odd edge case to be sure but I hit
it with my new NIR CF pass for NAK.

8b37046765 nir/builder: Handle i2b conversions specially in nir_type_convert
The shaders affected here are ones that were previously affected when
i2b was unconditionally lowered in opt_algebraic. There are a few places
where some transformations happen in a different order, so some
algebraic patterns are missed.

9a225415e3 nir/builder: Short-circuit in nir_type_convert if no conversion happens
If both types are the same or both are integer types with the same bit
size, no actual conversion happens and nir_type_conversion_op() will
return nir_op_mov.  In this case, there's no point in emitting the move
and we can just return src instead.

d95f9d189a nir: Introduce a nir_vec_scalars() helper using nir_ssa_scalar.
Many users of nir_vec() do so by nir_channel()-ing a new ssa defs as movs
from other vectors to put the new vector together, which then just have to
get copy-propagated into the ALU srcs and DCEed away the temporary movs.
If they instead take nir_ssa_scalar, we can avoid that extra work.

This saves a bunch of generated code to pack up the extra NULLs to get to
4 args, and saves executing the conditions in nir_build_alu() to then skip
those NULLs.
