intel/vec4: sel.cond writes the flags on Gfx4 and Gfx5

This is the equivalent of idr's
intel/fs: sel.cond writes the flags on Gfx4 and Gfx5

except for the vec4 backend.

This fixes buggy rendering seen with crocus on a qt trace.

v2 (idr): Trivial whitespace change.  Add unit tests.

v3: Fix type in comment in unit tests.  Noticed by Jason and Priit.

intel/fs: sel.cond writes the flags on Gfx4 and Gfx5

On Gfx4 and Gfx5, sel.l (for min) and sel.ge (for max) are implemented
using a separte cmpn and sel instruction.  This lowering occurs in
fs_vistor::lower_minmax which is called very, very late... a long, long
time after the first calls to opt_cmod_propagation.  As a result,
conditional modifiers can be incorrectly propagated across sel.cond on
those platforms.

No tests were affected by this change, and I find that quite shocking.
After just changing flags_written(), all of the atan tests started
failing on ILK.  That required the change in cmod_propagatin (and the
addition of the prop_across_into_sel_gfx5 unit test).

Shader-db results for ILK and GM45 are below.  I looked at a couple
before and after shaders... and every case that I looked at had
experienced incorrect cmod propagation.  This affected a LOT of apps!
Euro Truck Simulator 2, The Talos Principle, Serious Sam 3, Sanctum 2,
Gang Beasts, and on and on... :(

I discovered this bug while working on a couple new optimization
passes.  One of the passes attempts to remove condition modifiers that
are never used.  The pass made no progress except on ILK and GM45.
After investigating a couple of the affected shaders, I noticed that
the code in those shaders looked wrong... investigation led to this
cause.

v2: Trivial changes in the unit tests.

v3: Fix type in comment in unit tests.  Noticed by Jason and Priit.

v4: Tweak handling of BRW_OPCODE_SEL special case.  Suggested by Jason.

panfrost: Leverage Bifrost's 2*src blend factor

Bifrost adds a value for the C factor equaling 2*src. This does not
correspond directly to API blend modes so it is not too useful in
general. However, it's required for src*dest + dest*src blending to be
done in hardware instead of a blend shader. GFXbench uses that blend
mode, so it must be important ;-)

panfrost: Add basic fixed-function blending tests

Add unit tests for the fixed-function blending helpers in pan_blend.c.
Each test consists of a Porter-Duff blend mode and the associated
hardware state. In this commit, we add tests for the most common modes.

For motivation, this code has NOT been properly tested in CI. True,
functional correctness of the blend module as a whole is tested by
dEQP-GLES3.functional.fragment_ops.blend.* among other integration
tests. However, this testing is insufficient to check for regressions.
Crucially, the following broken patch would clear CI:

   bool pan_can_fixed_function(...) {
      return false;
   }

In that case, blend shaders are used 100% of the time, which will
regress performance horribly but still pass dEQP. The only clue
something went wrong would be some traces changing checksum due to the
fixed-function blender producing slightly different output than
equivalent blend shaders. By unit testing the fixed blend path, we
ensure we always use the fixed-function path when we expect it to.

Similarly, using incorrect values for the blend metadata may not affect
functional correctness but will increase power consumption. Let's check
all the data we export to drivers.

Note: due to additive commutativity, there are many pairs of equivalent
Mali blend modes. Unfortunately, the vendor is... inconsistent about how
to resolve ambiguous modes. Our algorithm for computing modes is
correct; the "preferred" values are left in comments since otherwise our
tests fail despite correct code. I want to blame Bifrost for this, but
Midgard was patient zero.

Revert "nir/algebraic: Convert some f2u to f2i"

Per https://gitlab.freedesktop.org/mesa/mesa/-/issues/5178#note_1019666,
the assumption fundamental to this optimization is false.  Section
2.4.1 (Float to Integer) of Ivy Bridge PRMs describes the situation.
The wording of the section is somewhat confusing (because it doesn't
clearly delineate between signed and unsigned integers), but the last
two rows of the table make it clear that F->UD conversion clamps
negative float values to 0.

All other hardware mentioned in that thread seems to behave the same
way.

The real problem is that, with hardware that behaves in this ways,
converting f2u(2147483648.0) to f2i(2147483648.0) changes the bit pattern
that would be produced from 0x80000000 to 0x7fffffff.

tu: Read some input attachments directly

It can happen that the user reads an input attachment as the first use
of that attachment. In that case there are no subpass dependencies
required at all, because there could be a pipeline barrier before the
renderpass instead, and in any case we assume that dependencies with the
first subpass as a destination can be executed only once outside the
renderpass. The result is that we only do a CACHE_INVALIDATE once
before the entire renderpass, but it's actually required after each GMEM
load, because input attachments read GMEM through UCHE and those writes
to GMEM invalidate UCHE.

While we could add the missing CACHE_INVALIDATE "by hand" somehow, it
turns out it's actually just as easy to do an optimization the blob
does, where it simply doesn't patch those input attachments and reads
them directly instead. This means we can skip allocating memory in GMEM
for them entirely in some circumstances.

This fixes e.g.
dEQP-VK.api.copy_and_blit.core.resolve_image.whole_array_image.4_bit

broadcom/compiler: rewrite partial update liveness tracking

The code we had for this was a work in progress and not finished. Also,
it was geared towards partial writes caused by output packing (i.e.
fp16) and was ignoring partial updates caused by conditional writes,
which are far more common in our case.

for their spills.

broadcom/compiler: make spills of conditional writes also conditional

A spill of a conditional write generates code like this:

mov.ifa t5000, 0
mov tmud, t5000
nop t5001; ldunif (0x00008100 / 0.000000)
add tmua, t11, t5001

Here, we are spilling t5000, which has a conditional write, and we
produce an inconditional spill for it. This implicitly means that
our spill requires a correct value for all channels of t5000.

If we do a conditional spill, then we emit:

mov.ifa t5000, 0
mov tmud.ifa, t5000
nop t5001; ldunif (0x00008100 / 0.000000)
add tmua.ifa, t11, t5001

Which only uses channels of t5000 that have been written by the
instruction being spilled.

By doing the latter, we can then narrow down the liveness for t5000
more effectively, as we can use this to detect that the block only reads
(in the tmud instruction) the values that have been written previously
in the same block (in the mov instruction). This means that values in
other channels are not used, and therefore, we don't need them to be
alive at the start of the block. This means that if this is the only
write of t5000 in this block, we can consider that the block
completely defines t5000.

virgl/ci: Rebalance concurrency

Crosvm deals with virtio-gpu commands sequentially, so parallelization
in the host doesn't help much.

Also, too much parallelization in the guest causes some tests to time
out.

So reduce the number of dEQP instances being run concurrently, make sure
we dont limit the number of CPUs being used in the host and schedule
more jobs in CI to keep the times below 10 minutes.

dEQP isn't high on rendering, but that is in the critical path as all
dEQP processes are waiting for Crosvm to single-threadedly service their
requests.

etnaviv: always try to create KMS side handles for imported resources

By creating the KMS side handles we allow GBM to return the proper KMS
side GEM handles for imported buffers. Always creating the KMS side
handles adds a bit of overhead, as we don't need them on all imported
resources, but seems like the most robust solution for now.

renderonly: don't complain when GPU import fails
