nir: Rearrange and-compounded float compares
...
If both comparisons are used as sources for instructions other than the
iand, this transformation is detrimental. If the non-identical value in
both compares is constant, the fmin or fmax will be constant-folded
away, so the transformation is always a win.
It is interesting to me that on Iron Lake only 81 shaders have
instruction counts changed, but 726 shaders have cycle counts changed.

st/glsl_to_nir: disable io lowering and array splitting of fs inputs
...
We need this to be able to support the interpolateAt builtins in a
sane way. It also leads to the generation of more optimal code.
The lowering and splitting is made conditional on lower_all_io_to_temps
because vc4 and freedreno both expect these passes to be enabled and
niether support glsl 400 so don't need to deal with the interpolateAt
builtins.
We leave the other stages for now as to avoid regressions. Ideally we
could remove the stage checks and just set the nir options correctly
for each stage. However all gallium drivers currently just use return
the same nir compiler options for all stages, and it's probably more
trouble than its worth to change this.
