These where found when going through the mysteriously
high gains I got from the VRP pass. My pass was doing
bad things, but upon inspection I found these.
First patch is benefitial, the rest shows no change
on a shader-db run on my system.
Thomas Helland (3):
nir: Simplify fne(fneg(a), a) -> fne(a, 0.0)
nir: Simplify feq(fneg(a), a)) -> feq(a, 0.0)
nir: Simplify ine/ieq(ineg(a), a) -> ine/ieq(a, 0)
