anv: Reject modifiers on depth/stencil formats

6790397346cc added code which attempts to reject modifiers on
depth/stencil formats but it was placed after the early return for depth
and stencil aspects.  This commit moves it up so it actually works.

Of course, this doesn't actually matter because the only user of any of
the modifiers stuff is the WSI code and it will never do anything with
depth/stencil.

nir: Mark fmin and fmax as commutative and associative

Per the resolution of Khronos GLSL issue 80
(https://github.com/KhronosGroup/GLSL/issues/80).  Spec updates have not
landed yet, but I'll get to it soon. :)

The extra hurt shaders on Gen8+ are a handful of shaders that see things like

    bcsel(fmin(b - a, a - c) >= 0, x, y)

converted to

   bcsel(a >= b && c >= a, x, y)

The former can be generated as a CSEL instruction.  If either b - a or a
- c is used elsewhere in the shader, this saves an instruction.

All Haswell+ platforms had similar results. (Ice Lake shown)

Revert "gallium: Fix big-endian addressing of non-bitmask array formats."

This reverts the functional part of commit
d17ff2f7f1864c81c1e00d04baf20f953c6d276a, leaving the unit test for
mesa/pipe agreement on what's an array.

The issue is that the util_channel_desc.shift values on array formats are
not used for bit addressing in memory, they're bit addressing within a
word treating a pixel of the format as a native type, as seen by
llvmpipe's use of the values to do shifts (see
lp_build_unpack_arith_rgba_aos() for example).  This means the values are
nonsensical for 3-byte RGB, but then llvmpipe doesn't expose those formats
so it works out.

I still want to clean up our big-endian format handling at some point, but
let's fix the s390x regression first, sort out our format unit tests in
CI, then be able to refactor with confidence.

Fixes: d17ff2f7f186 ("gallium: Fix big-endian addressing of non-bitmask array formats.")
Closes: #2472

r600/sfn: Add lowering arrays to scratch and according instructions

Make use of the scratch space for arrays that are larger then 100 elements.
Since for IO r600 is vector based, there is a bit of a scratch space waste
here for arrays that use types smaller then vec4.

r600/sfn: add register remapping

Make use of the live range evaluation to merge registers. Since the
live ranges are evaluated for register indices, the algorithm is not
optimal, but for most piglits up to glsl-3.3 it does the job.

r600/sfn: add live range evaluation for the GPR

The algoritm is basically a copy of the TGSI implementation without the
array bits.

r600/sfn: Add the VS in and FS out vectorization

Since the nir default implementation doesn't support vectorizing the VS
inputs and FS outputs, additional lowering passes are added here to do
just that. The work is based on the Timothy Arceri's related work.

r600: enable NIR backend DEBUG flag for supported architectures

When NIR is enabled, a few features that are not yet supported will be
explicitely disabled.

r600/sfn: Add a basic nir shader backend

This commit adds support for vertex and fragment shaders from NIR, and
support for most TEX and ALU instructions.

Thanks Dave Airlied for adding support for a number of ALU instructions.

v2: fix compilation with gcc-6
v3: rebase: use mesa/core glsl_type_size function
