3c03718fd7 nir: fix clip/cull_distance_array_size in nir_lower_clip_cull_distance_arrays
This fixes a GPU hang on radeonsi.

It only works if optimizations have already been run.

4e3d69ad07 nir/algebraic: Simplify a contradiction that can occur in __flt64_nonnan
The pattern is added to opt_algebraic because, for example, comparisons
with constant 0.0 will produce (a1 < 0).

Even with a pass that optimized Boolean expressions, I think this would
be very difficult to automatically recognize and optimize.

1d36af9338 nir/algebraic: Generalize some and-of-shift-right patterns [v2]
Generalizes some of the patterns from 76289fbfa8 and 905ff86198.  In
particular, some of the soft-fp64 code generates (a & 0x7fffffff) << 1
when constant 0.0 is compared (flt or feq).

v2: Reduce the set of added patterns to those that actually help
something.  This reduces the size of the state transition tables by
about 29k.  Suggested by Jason.  Remove the existing patterns that this
commit subsumes.

d6d63aec18 nir/algebraic: optimize ior(ine(a, 0), ine(b, 0)) to ine(ior(a, b), 0)
Like 70f9e2589e.  Also scrub the unnecessary size qualifier in both
replacement patterns.

This occurs in a handful of places in the soft-fp64 code, and that is
the primary reason for the change.

Perhaps the patterns that generate umin should be conditioned on
something, but I'm not sure what.  lower_bitops might cover the cases
that matter, but it seems ugly.

acd0dd3b4b nir/lower_double_ops: relax lower mod()
Currently when lowering mod() we add an extra instruction so if
mod(a,b) == b then 0 is returned instead of b, as mathematically
mod(a,b) is in the interval [0, b).

But Vulkan spec has relaxed this restriction, and allows the result to
be in the interval [0, b].

For the OpenGL case, while the spec does not allow this behaviour, due
the allowed precision errors we can end up having the same result, so
from a practical point of view, this behaviour is allowed (see
https://github.com/KhronosGroup/VK-GL-CTS/issues/51).

This commit takes this in account to remove the extra instruction
required to return 0 instead.

always remove an upcast followed by a down cast, that is:

  f2fmp ( f2f32 (a) )  ->  a

In the other direction, f2f16 loses precision and can't be undone by a
f2f32.  However, by definition it's always safe to elminate f2fmp:

immediately converted back to a 32-bit float again. Normally this
would be a lossy conversion and so it would be visible to the
application, but if the conversion is generated as part of the mediump
lowering process then this removal doesn’t matter. The opcode is
eventually replaced with a regular f2f16 in the late optimisations so
the backends don’t need to handle it.

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.

37125b7cc2 r600/sfn: Add lowering UBO access to r600 specific codes
r600 reads vec4 from the UBO, but the offsets in nir are evaluated to the component.
If the offsets are not literal then all non-vec4 reads must resolve the component
after reading a vec4 component (TODO: figure out whether there is a consistent way
to deduct the component that is actually read).

8d07d66180 glsl,nir: Switch the enum representing shader image formats to PIPE_FORMAT.
This means you can directly use format utils on it without having to have
your own GL enum to number-of-components switch statement (or whatever) in
your vulkan backend.

Thanks to imirkin for fixing up the nouveau driver (and a couple of core
details).

This fixes the computed qualifiers for EXT_shader_image_load_store's
non-integer sizeNxM qualifiers, which we don't have tests for.

f5619f5073 pan/midgard: Turn Z/S stores into zs_output_pan intrinsics
Midgard can't write depth and stencil separately. It has to happen in
a single store operation containing both. Let's add a panfrost specific
intrinsic and turn all depth/stencil stores into a packed depth+stencil
one.

Note that this intrinsic is not yet handled in emit_intrinsic(), but
we'll address that later.

65610ec774 gitlab-ci: Add ppc64el and s390x cross-build jobs
Using LLVM 8 for ppc64el and 7 for s390x (which hits some coroutine
related issues with LLVM 8).

There are some test failures we need to ignore for now. Also, the
timeout needs to be bumped from the default 30s for some tests, because
they can take longer under emulation.
