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

The following probable MSVC bug clued us in to some probably-unexpected behavior:
https://developercommunity.visualstudio.com/t/Incorrect-SSE-code-for-minmax-with-NaNs/10687862

Change the logic here so that we're always starting with NANs and use
fmin/fmax, which have more-deterministic handling of NANs. If one argument
is NAN, the non-NAN argument is returned. The previous code would've returned
the second argument if one was NAN.

c39896b17b nir: Use getters for nir_src::parent_* 
First, we need to give the parent_instr field a unique name to be able to
replace with a helper.  We have parent_instr fields for both nir_src and
nir_def, so let's rename nir_src::parent_instr in preparation for rework.

This was done with a combination of sed and manual fix-ups.

Then we use semantic patches plus manual fixups:

6c1d32581a nir: Drop nir_alu_dest 
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.
