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.
