These do not convey any additional information, and fail to account for
shrinking. In particular, a 64-bit writemask with .keephi would fail to
disassemble and instead trip the assertion, since that would be the ZW
components. Just delete the broken code.

Otherwise, we can get vec3 with u2u32 with 64-bit sources which we need lowered.
Since our current approach is "scalarize all 64-bit ops", we need to check for
conversions too.

Logically at the same part of the compile pipeline as clause scheduling on
Bifrost. Lots of similarities, too. Now that we generate flow control only as a
late pass, various hacks in the compiler are no longer necessary and are
dropped.

Test that we correctly track the scoreboard, helper invocations, reconvergence,
and ends and insert NOPs to effect this expected flow control.
As the pass inserts NOPs but does not otherwise modify the shader, this is easy
to test with well-defined behaviour of the pass.

On Bifrost, to terminate helper threads we set the td bit on the clause. On
Valhall, we need to use the .discard flow control. Extend the flow control NOP
insertion to insert NOP.discard where necessary to terminate helper threads.
This should reduce wasted work in fragment shaders.
This requires fairly involved data flow analysis, but the handling here should
be optimal.

To set flow control modifiers correctly and efficiently, we need a pass that

The current helper termination analysis code is hardwired for clauses, so it
won't work for Valhall. However, the bulk of it is dataflow analysis which is
portable between Bifrost and Valhall. Export the interesting bits so we can
reuse them on Valhall.

We need to insert dependencies for varyings and memory access. Currently, the
Bifrost scoreboarding pass just treats these as barriers, but this is too heavy
handed. Extend the scoreboard data structure so we can do better.

The Polaris10 in CI has been getting insta-hangs when starting dEQP.
Let's give it 5 attempts to get its act together, as it won't affect
the run time dramatically (max 5 minutes), but will provide more
reliable results for developers.
Tracking of hangs (and many other issues) is done through scrapping the
execution logs, processing them to find these issues, then pushing the
data to influxdb. This allows us to plot the failure rate over time,
and see if the situation is getting better or worse.

This function allows to only scalarize instructions down to a desired
vectorization width. nir_lower_alu_to_scalar() was changed to use the
new function with a width of 1.
Swizzles outside vectorization width are considered and reduce
the target width.
This prevents ending up with code like
vec2 16 ssa_2 = iadd ssa_0.xz, ssa_1.xz
which requires to emit shuffle code in backends
and usually is not beneficial.

The callback allows to request different vectorization factors
per instruction depending on e.g. bitsize or opcode.
This patch also removes using the vectorize_vec2_16bit option
from nir_opt_vectorize().

NIR already has the necessary lowering, and the GLSL lowering violates
GLSL IR validation rules. Once quadop lowering was turned off, the IR
validation at the end of the compile path on DEBUG builds caught the
problem.
In order to move the lowering to NIR, though, we need to make sure that
drivers supporting these functions actually have the lowering flag set.
xfails added for t860, where apparently this tickles a variety of existing
64-bit bugs in the backend.

It looks like atomics are slow on compressed surfaces so when enabling
compression for storage images that can be possibly used for atomic
operation hinders performance. Lets just disable compression in this
scenario.
