ac/nir: use ordered float comparisons except for not equal
Original patch from Timothy Arceri, I have just fixed the
not equal case locally.
This fixes one important rendering issue in Wolfenstein 2
(the cutscene transition issue).
RadeonSI uses the same ordered comparisons, so I guess that
what we should do as well.
