6148e3aae7 ("mesa: Fix ctx->Texture.CubeMapSeamless") introduced a hack, where
seamless cube maps would be requested even for GLES2 contexts despite the spec,
on the assumption that GLES2 gallium drivers would ignore the bit. But that
requires Gallium drivers to know what GLES version they advertise, which is a
horrible layering violation. When the commit was written 8 years ago, there were
classic drivers to contend with so it made sense as a fix to get GLES 3.0 up and
running. With classic drivers gone, it's time to sunset the hack and restore the
intended behaviour by setting ctx->Texture.CubeMapSeamless only once we know the
version.
In addition to fixing a semantic issue in the Gallium contract and preventing a
regression from the next commit, this fixes cube maps on Mali-T720 under
Panfrost. In general, Panfrost supports GLES3 (and honours the seamless flag
everywhere) but on T720 we only advertise GLES2 due to missing MRT support on
older Midgard devices, so we need the flag set properly to distinguish these
cases.

.lava-test hidden job was setting the HWCI_TEST_SCRIPT variable to deqp
runner. But that is not always the case. When we run piglit traces jobs,
we use piglit-traces.sh instead, for example.
Splitting into:
- .lava-test-deqp (deqp-runner + deqp)
- .lava-traces (deqp-runner + piglit)
- .lava-piglit (piglit-runner + piglit)

Previosuly it was assumed that primitives where always converted to
triangles if the driver did not support all primitives, however that's
not true for a driver that supports quads but not quad strips.

Since 50b82ca818 ("nir/lower_blend,agx,panfrost: Use lowered I/O"),
nir_lower_blend needs to be called after lowering I/O rather than before.
Furthermore, after lowering blend, we need (in general) to lower the resulting
load_output intrinsics. Now that we have a proper preprocess_nir hook, there is
a natural place in panvk_vX_shader to do this.

This is a flag-day change to how we compile. We split preprocessing NIR into a
separate step from compiling, giving the driver a chance to apply its own
lowerings on the preprocessed NIR before the final optimization loop. During
that time, the different producers of NIR (panfrost, panvk, blend shaders, blit
shaders...) will be able to (differently) lower system values.

See previous commits for justification. Later, we'll split up NIR processing in
a few steps to give the caller a chance to lower the sysval, at which point the
goofy inputs here will go away.
v2: Only lower in fragment shaders. Likely harmless to run elsewhere but still
wrong because the location enum is defined per-stage.

This uses the new NIR sysvals to avoid materializing magic sysvals in the
driver, getting us closer to the Ekstrand Rule.
v2: Only lower for fragment shaders. Lowering in vertex shaders should be a
no-op, except that FRAG_RESULT_SAMPLE_MASK shadows a VARYING_SLOT for fog
coords, causing v1 of this patch to regress fog. Caught by the G52 piglit job in
CI. Thank you, Marge.

These two switches are redundant.
Furthermore, bi_tex_op could previously assume its input was a supported texop,
so it returned undefined values for unsupported texops. Now, without the guard
in front of it, bi_tex_op should check for supported texops, so we need to drop
the unsupported texops from the switch.

This is really dumb.
But this fixes arb_shader_language_420pack-active-sampler-conflict on v7 which
otherwise dereferences a null pointer trying to access the nonexistant texture
arrays, or DATA_INVALID_FAULTs if you give it a texture array filled with
zeroes. But it seems happy if you bind in null textures. This is dumb but less
faults in Piglit is good for reducing flakes.

mesa/st doesn't like to use 24-bit textures, preferring RGBX over true RGB even
for texture views where this isn't valid. Given how silly true RGB is in
practice, I'd rather drop support and fix texture views than go against the
grain and risk more issues down the line since nobody else in tree is testing
these paths and apps really shouldn't be caring.
Fixes page faults in arb_texture_view-rendering-formats_gles3 which tries to
sample an R8G8B8_UINT texture with a R8G8B8X8_UNORM view in one subcase. That
test is now passing reliably.

This is signed, not unsigned. We were already passing negatives and silently
relying on 2's complement and C to do the right thing. But that's silly. We
should just, actually do the right thing.

We just want a bit-exact transfer for integers. Using .auto32 accomplishes this
without any clamping shenanigans. Fixes gl-3.0-vertexattribipointer.
Note we can't use .auto32 unconditionally, since reading a uint vertex as float
is supposed to convert (or something like that, gl-2.0-vertexattribpointer tests
the bad case at any rate).

draw->index_bounds_valid tells drivers that the values of min_index/max_index
are set correctly and can be used e.g. to allocate memory for varyings. If set
incorrectly, the GL promises badness.
But, with primconvert, we go mucking with index buffers and then never update
the bounds. So it doesn't matter if the original index bounds were valid, we
can't promise the original bounds are *still* valid. If we were trying to
optimize CPU overhead, we could try to preserve the new min/max index but seeing
as only older Mali cares about this flag, and if you're using primconvert you're
already screwed, I'm not too inclined to go rework primconvert.
Fixes* page faults in primitive-restart-draw-mode on Mali-G52 for GL_QUAD_STRIPS
and GL_POLYGON, which hit the primconvert path. The full dmesg splat looks like:
[ 5438.811727] panfrost ffe40000.gpu: Unhandled Page fault in AS0 at VA 0x000000100A16BAC0
Reason: TODO
raw fault status: 0x25002C1
decoded fault status: SLAVE FAULT
exception type 0xC1: TRANSLATION_FAULT_1
access type 0x2: READ
source id 0x250
Notice that a high bit is randomly set in the address, this is trying to read
a varying from the actual varying buffer in the vicinity of 0xa16bac0. What's
actually happening is that we're trying to read index #0 despite promising the
driver a minimum index of 2, causing an integer underflow as we try to read
index -2, or as the hardware sees, 4294967294.
As long as we stop lying to panfrost about the bounds being correct, panfrost is
able to calculate the real (post-primconverted) bounds on its own, fixing the
test.
* Alternatively, maybe Panfrost should just ignore this bit, in which I don't
know why we have it in Gallium, since it's probably not conformant to fault on
out-of-range glDrawRangeElements.
