Unlike ufind_msb, ifind_msb is only defined in NIR for 32-bit values, so
no @32 annotation is required.

When enabled, on gfx12 plus, we will add the sync nop instruction after
each instruction to make sure that current instruction depends on the
previous instruction explicitly.
This option will help us to get a hint if something is missing or broken
in software scoreboard pass.

This mainly lets the software scoreboarding pass correctly mark the
instructions, without needing to resort to fragile manual handling in
the generator.
We can also make small improvements. On Gfx 8LP-12.0, we no longer have
the restrictions about DWord alignment, so we can simply write each half
into its intended location, rather than writing it to the low DWord and
then shifting it in place.

I originally thought that we were intentionally emitting the legacy
opcodes here to make them opaque to the optimizer, so that it wouldn't
eliminate the explicit type conversions, as they're actually required
to do the quantization. But...we don't actually optimize those away
currently anyway. So...go ahead and use the helpers for consistency.

With the previous patch, we no longer need to special case this, as we
emit a MOV with an HF source, rather than F16TO32 with an UW source,
on all platforms that need scoreboarding.

This gets us a MOV at the IR level on Gfx8+ which should be more
optimizable than F16TO32. It also removes confusion about which
pipe which the instruction will run on.

We can just use the new builder helpers to get the optimization
advantages of a MOV on Gfx8+ while also getting the necessary F32TO16
on Gfx7.x and yet not worry too hard about it.

For converting half-float to float, we currently emit BRW_OPCODE_F16TO32
with a UW source, to match legacy Gfx7 behavior. In the generator, this
becomes a MOV with a HF source on Gfx8+. Unfortunately, this UW source
confuses the scoreboarding pass into thinking it's an integer source,
leading to incorrect SWSB annotations on Alchemist.
We should ultimately fix the IR to stop being so...legacy...here, but
this is the simplest fix for stable branches.
Fixes misrendering in Elden Ring and likely Sekiro: Shadows Die Twice.

The HW can technically execute 16-bit operations, but the restrictions on
16-bit ALU ops are so great that it ends up not being a win for
GLES-on-Vulkan to lower mediump to 16-bit operations, at least with the
current state of the Intel compiler. This brings zink-on-anv in line with
iris and angle-on-anv for mediump behavior (ANGLE uses RelaxedPrecision,
which we ignore).

Our TGL machines are currently slightly oversubscribed (max. 17 jobs in
a pipeline on 15 DUTs). They're also currently suffering from
thermally-induced GPU throttling (being investigated), and a
thundering-herd network load effect: as all 15 jobs start at once, we
end up saturating one of our network links.
The combination of all three of these things means that TGL is often our
long pole in CI runs. Until we can ameliorate the two issues
constraining throughput (and a third where an unreliable hardware UART
sometimes kills jobs when it shouldn't), halve the workload so we at
least have some breathing room to absorb them.

Seems to fix a hang in the following titles :
- Age of Empire 4
- Monster Hunter Rise
where the HW is hung on a PIPE_CONTROL after a GPGPU_WALKER but no
MEDIA_INTERFACE_DESCRIPTOR_LOAD was emitted since the switch from 3D
to GPGPU.
This would happen in the following case :
vkCmdBindPipeline(COMPUTE, cs_pipeline);
vkCmdDispatch(...);
vkCmdBindPipeline(GRAPHICS, gfx_pipeline);
vkCmdDraw(...);

For GLSL, we want to optimize code like
memoryBarrierBuffer();
controlBarrier();
into a single scoped_barrier intrinsic for the backend to consume. Now that
backends can get scoped_barriers everywhere, what's left is enabling backends to
combine these barriers together. We already have an Intel-specific pass for
combining memory barriers; it just needs a teensy bit of generalization to allow
combining all sorts of barriers together.
This avoids code quality regression on Asahi when switching to purely scoped
barriers. It's probably useful for other backends too.
