For code like:
if (cond) {
val = load()
}
use(val)
The "use(val)" now has a similar cost to a use inside the IF.

* optimize not(compare(a,b)), nir_opt_algebraic does this only if the
comparison result is used only once, but on a vector arch we still get
an advantage when doing this, because it reduces dependencies.
* optimize b2f32(compare(a,b)), this is r600 specific

This was incorrect (it also lowered int64 reductions/scans), and the only
user can just use the general callback to precisely only lower what it wants.

This was added with the goal to eventually replace the per
pass subgroup/ballot size options, but that won't work because
some backends don't have a fixed subgroup size across the compilation
process.
It was also mostly added to hack around mesa state tracker behavior,
and we have a better solution there now.

We skip iterations with ifs.
These can be optimized aways after the subgroup size is known.
Every driver should do that because applications depend on it anyway.

If the offset is iadd(iadd(iadd(a, 1), b), -1), try_extract_const_addition
will create a dead iadd(a, b) and claim that it didn't modify the shader.

Commit d2f7b6d5 changed the BLEND_STATE update process so that only
the used render targets will be updated. This mostly works fine, but
in cases when the Dual Source Blending was used previously, we still
must turn it off to avoid the undefined behavior that leads to hangs.

Just to stay consistent. We might want to use them instead of declaring
them inside meson, but I'd rather prefer we have a consistent list across
all crates and that's easier done in meson.

On a fossil from the blender 4.5.0 vulkan backend, this improves compile
times in nak by about 17%. Compile time of other shaders improves by a
more modest 1.2%.

This lets us control how much logging we want Mesa to do, which is
useful in CI where we don't want to collect lots of log spam that then
has to be saved somewhere.
