821e7a4d32 nir: Separate a weird compare with zero to two compares with zero 
min(a+b, c+d) >= 0 becomes (a+b >= 0 && c+d >= 0).

No shader-db changes, but it does prevent 6 to 12 instruction
regressions in the next patch on all measured Intel platforms.

68420d8322 nir: Simplify min and max of b2f 
v2: Rebase on almost 2 years.  Require that one of the arguments to fmin
or fmax be used only once.  This prevents some regressions.

3941cba0f7 nir: Be more conservative about rearranging or-compounded compares 
If both comparisons are used as sources for instructions other than the
ior, 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.

283e25102b 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.
