There's already code to verify that any compacted instruction
that we produce is equivalent to the original uncompacted
instruction -- including detailed output if it fails.
This patch enables this verification in debug build and will
abort in case it fails.

* ballot{,_relaxed}'s src[0] must always be a 32-bit value.
* read_invocation's src[0] must always be at most 32-bit value. While
the HW instruction always operates on a 32-bit value, it's important
to remember that it's just a data movement operation, so garbage in
the high bits of a 32-bit value representing a narrower value don't
present an issue.

All mature drivers report shader statistics in various places. GL drivers use
util_debug for shader-db's report script. VK drivers use executable statistics
feeding the report fossil script. Many drivers also have a magic env var to
dump the stats to stdout/stderr in addition to these standard forms.
Implementing any of these 3 reports requires doing brittle string processing in
C (GL, stdout) or piles of boilerplate (VK). Additionally, the logic gets
duplicated in every driver and duplicated between GL and VK.
And to add insult to injury, the information is duplicated *again* in the report
fossil script :'(
This commit introduces a new 'shader statistic framework' that aims to unify
statistics reporting across all drivers and across GL&VK. With the new approach,
a common XML file defines all the statistics for the tree. The common code
introduced here then autogenerates from that XML file an appropriate C header.
The header contains a C struct for each ISA, and autogenerated print/report
functions. Minimal driver integration is required: just filling out the stats
struct and calling the appropriate functions.
In this MR, 3 driver families are added as examples. Panfrost/PanVK and
Asahi/Honeykrisp are added as "complete" examples. Neither Vulkan driver
reported nontrivial executable statistics; with these changes, both report all
the same statistics that the GL drivers report. Turnip is also added partially -
it's not plumbed into ir3/gallium yet but just using the XML reduces boilerplate
a ton for Vulkan statistics.
[It is intended for this XML to be consumed also by shader-db's python scripts,
but that's not done here.]

This seems to fix some artifacts, but we're not sure why, so it might not
be a correct or optimal solution.

The old code got the accumulation a bit wrong. For one thing, it always
accumulates with whatever was there instead of resetting to empty each
time. For another, it sets with with y and height with x when it writes
back to the resource. This is also all too complicated because it
converts between pipe_box, u_rect, and VkRect2D on every iteration.
Instead, there are helpers in util/box.h which will do most of this work
for us and they're correct. Let's just use them to get rid of the bugs
and make everything simpler and more obvious at the same time.

The old calculations are wrong. They add width+x and call that a width
the same with y and height. This is wrong but it's wrong in a way that
only ever increases damage so we never noticed it. However, util/box.h
has helpers for these operations which don't have this bug. Let's use
them and make the code simpler, more obvious, and correct. We also
weren't flipping the damage like we're supposed to and that was most
likely not getting noticed because of the over-damage.

In case of constant lowering with halfswizzle sources, we were selecting
h01 causing an invalid instruction error to be yield later.
This can only be hit by conversion instructions and shouldn't be seen in
the wild (as this should be eliminated before entering the backend).

If we pass zink=false to pipe_loader_drm_probe_fd, it could happen that
a Gallium driver that had been already discarded because of not
supporting the graphics CAP will be chosen.
To avoid that, explicitly ask pipe_loader_drm_probe_fd to choose the
zink Gallium driver.

Exposing a rendernode from a supported driver is not a sufficient
matching criteria to qualify as the render part of a renderonly
device, as the rendernode might only expose compute or 2D accel
capabilities.
Look for a screen that actually supports gallium graphics operations
to qualify as a renderonly screen.

based on capabilities.
