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

We don't have v_permlane64_b32 yet, but we can still optimize it using
shared vgprs. Using the DPP16 row mask, we can even avoid writing exec.

With v0 input/output and v24/v25 as shared vgprs, this results in:
v_mov_b32_dpp v24, v0 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf
v_mov_b32_dpp v25, v0 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf
v_mov_b32_dpp v0, v24 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf
v_mov_b32_dpp v0, v25 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf

2c51a8870d nir: add nir_vectorize_cb callback parameter to nir_lower_phis_to_scalar()
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
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.

4263b49778 ac/nir: remove ngg_scratch LDS ABI, allocate it in the lowering pass 
This is a cleanup.

Old gs LDS layout: [es outputs][gs outputs][scratch]
Old nogs LDS layout: [xfb/cull][scratch]

New gs LDS layout: [es outputs][scratch|gs outputs]
New nogs LDS layout: [scratch|xfb/cull]

The LDS scratch is moved to the beginning of the preceding buffer in LDS,
while the addresses in that LDS buffer are offset by the scratch size.
It effectively merges the LDS scratch with the preceding buffer in LDS.
Thanks to that, we no longer need the ngg_scratch ABI and the offset
in a user SGPR.

The lowering passes now return the LDS scratch size, which is used
by the drivers to determine the final LDS size.

The ngg_lds_layout SGPR is now unused without GS in RADV.
