d9eb9a3eef nir/opt_algebraic_tests: Make sure we test the same inputs on BE as LE. 
With the inexact signed zero support, we ended up with diverging inputs
producing diverging "all skipped" results for the matrix mul tests.

68f5bc4f12 nir/opt_algebraic_tests: Rename and use the enum result type more. 
As I introduced another layer of iteration for signed zero testing, the
former logic got unwieldy.  In fact, it was already unwieldy enough that I
forgot to clear all_skipped when the assert failed, allowing a failing
test to be marked UNSUPPORTED instead of XFAIL.

4fedf6bedd nir/lower_blend: Add advanced blending support 
Add support for advanced blending (VK_EXT_blend_operation_advanced and
GL_KHR_blend_equation_advanced), enabling around 40 advanced blend modes
including multiply, screen, overlay, HSL modes (hue, saturation, color,
luminosity), Porter-Duff modes, and extended modes like lineardodge
and vividlight.

Advanced blending slots into the existing blending logic alongside logic
operations and standard blending. The implementation supports both
premultiplied and non-premultiplied alpha for source and destination, and
provides three overlap modes (uncorrelated, conjoint, disjoint).

Move the blend equation helper functions (blend_multiply, blend_screen,
blend_overlay, etc.) from gl_nir_lower_blend_equation_advanced.c to a
new shared header file nir_blend_equation_advanced_helper.h.

These helpers implement the mathematical blend operations defined by
KHR_blend_equation_advanced and will be reused by the new NIR lowering
pass for VK_EXT_blend_operation_advanced.

macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
Using a string literal enclosed with the same type of quotation marks
with the outer f-string isn't supported on Python 3.10, which is
currently still with security maintainance.

This leads to syntax error when building Mesa with Python 3.10.

Fix this by alternating these string literals' quotation mark to '' (as
the outer f-string uses "").

43d998df84 nir: document that both input and output denorms have to be flushed 
This allows us to remove a * 1.0 or a - 0.0 if is_only_used_as_float.
We already rely on that.

7e93aebbec nir/constant_expressions: don't avoid unused source variable warnings 
The only use case for this was fddx/fddy and they are no longer alu
for good reasons. For current and future alu, unused sources don't make sense.

And if you really want it, you can still explicitly cast the variable to void.

246095da49 nir/meson: only try to generate the nir_opt_algebraic tests when requested 
Anything listed in a meson target's `output` is expected to exist once
the command has run. If it's missing, meson/ninja will run the command
again to try to generate it, resulting in a ton of files getting
re-generated/re-compiled for no reason.

4c30c44b75 nir: Generate unit tests for nir_opt_algebraic 
This catches a number of bugs in the current NIR algebraic optimizations
or opcodes implementations (as fixed in this series, or documented in the
XFAIL tests), and should prevent many future bugs from landing.

This required bumping the test timeout, because s390x is very slow to
emulate in CI.

Closes: #3338
