i965: Be more clever about setting up our viewport clip

Before, we were trusting in the hardware to take the intersection
of the viewport clip with the drawing rectangle.  Unfortunately,
3DSTATE_DRAWING_RECTANGLE is fairly expensive because it implicitly
does a full pipeline stall.  If we're a bit more careful with our
viewport clipping, we can just re-emit it once at context creation
time.

intel/compiler/fs: Implement ddy without using align16 for Gen11+

Align16 is no more. We previously generated an align16 ADD instruction
to calculate DDY:

   add(16) g25<1>F  -g23<4>.xyxyF   g23<4>.zwzwF   { align16 1H };

Without align16, we now implement it as:

   add(4) g25.4<1>F -g23.4<0,2,1>F  g23.6<0,2,1>F  { align1 1N };

   add(4) g26.4<1>F -g24.4<0,2,1>F  g24.6<0,2,1>F  { align1 1N };

where only the first two instructions are needed in SIMD8 mode.

Note: an earlier version of the patch implemented this in two
instructions in SIMD16:

   add(8) g25<2>F   -g23<4,2,0>F    g23.2<4,2,0>F  { align1 1N };
   add(8) g25.1<2>F -g23.1<4,2,0>F  g23.3<4,2,0>F  { align1 1N };

but I realized that the channel enable bits will not be correct. If we
knew we were under uniform control flow, we could emit only those two
instructions however.

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

This requires passing an extra argument to the lowering pass because
the KHR_blend_equation_advanced specification doesn't seem to define

in the shader source AFAICT).

In the long run we'll probably want to do state-dependent recompiles
based on the value of ctx->Color.BlendCoherent, but right now there
would be no benefit from that because the only driver that supports
coherent framebuffer fetch is i965 on SKL+ hardware, which are unable
to support the non-coherent path for the moment because of texture
layout issues, so framebuffer fetch coherency is always enabled for
them.
