486ea54184 nir/opt_algebraic: make bcsel(fcmp(b, a), b, a) -> fmin/fmax patterns exact 
These patterns need is_only_used_as_float because fmin/fmax might change NaN
patterns, while bcsel is bit exact. For the same reason, the replacement
must not add undefined results, so make the replacement NaN/inf preserving.

It's impossible to make them signed zero correct (-0.0 == +0.0),
so it's also important that the user alu doesn't care.

Otherwise, the only thing that matters is is whether a is NaN.

c5bf979d71 glsl: preserve inf/nan for precise/invariant 
Not sure if this is actually required, but it matches previous behavior in NIR,
and some piglit tests expect this.
Notably GL-CTS does not need this, so maybe piglit is just broken.

88a1887cc2 Revert "add VK CTS validation report for a0 interpolation fix" 
This reverts commit 4eeda739c4.

Looks like @ajax has been playing with claude "ai" and accidentally
committed and pushed things to main.

1. That doesn't belong here.
2. We shouldn't bypass MR review unless in emergency situations.

This seems like a good time to remind people to not have a push-able
upstream remote, to avoid an accidental `git push` or something else
doing that.
One way to do this is to change the push url like this, assuming your
upstream remote is called `origin` (default if you didn't pick
something else):

    git remote set-url --push origin invalid-url

`invalid-url` will fail if you try to push to it, catching your mistakes :)
