nir: add option to lower slt/sge/seq/sne
In freedreno these get implemented as the matching f* instruction plus a u2f to convert the result to float 1.0/0.0. But less lines of code to just let nir_opt_algebraic handle this for us, plus opens up some small window for other opt passes to improve (ie. if some shader ended up with both a flt and slt with same src args, for example). v2: use b2f rather than u2f Signed-off-by: Rob Clark <robclark@freedesktop.org> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Matt Turner <mattst88@gmail.com>
