ac: Add a shared interface between radv, radeonsi, LLVM and ACO
ac_shader_args will be similar to ac_shader_abi, except for being free
from LLVM-specific concepts and therefore capable of being shared
between LLVM and ACO. This will help us accomplish a few different
things:
- Decouple setting up SGPR and VGPR arguments from translating to LLVM,
so that we can reference these arguments in NIR lowering passes, which
will let us lower e.g. descriptor sets in NIR.
- Stop using radv-specific structures for things like determining the
chip generation in ACO.
In the end, we should replace ac_shader_abi with this structure +
driver-specific lowering passes.

We'll duplicate this in a header file in the next commit, and then
remove the original enum. Just rename it temporarily so that things
keep building.

GiMark benchmark from GpuTest has such code in VS:
out vec4 lightDir0;
out vec4 lightDir1;
...
lightDir0.xyz = lp0 - vVertex.xyz;
lightDir1.xyz = lp1 - vVertex.xyz;
In FS:
float distSqr = dot(lightDir0, lightDir0);
So due to the usage of uninitialized .w channel in the dot product,
distSqr may become undefined which results in many black dots
in the test on Iris.
In https://www.geeks3d.com/forums/index.php/topic,6242.0.html
developer stated that this benchmark most likely won't be updated.

radv: create a fresh fork for each pipeline compile
In order to prevent a potential malicious pipeline tainting our
secure compile process and interfering with successive pipelines
we want to create a fresh fork for each pipeline compile.
Benchmarking has shown that simply forking on each pipeline
creation doubles the total time it takes to compile a fossilize db
collection. So instead here we fork the process at device creation
so that we have a slim copy of the device and then fork this
otherwise idle and untainted process each time we compile a
pipeline. Forking this slim copy of the device results in only a
20% increase in compile time vs a 100% increase.
Fixes: cff53da3 ("radv: enable secure compile support")
This will be used to create a communication pipe between the user
facing device and a freshly forked (per pipeline compile) slim copy
of that device.
We can't use pipe() here because the fork will not be a direct fork
of the user facing process. Instead we use a previously forked
copy of the process that was forked at device creation in order to
reduce the resources required for the fork and avoid performance
issues.
Fixes: cff53da374 ("radv: enable secure compile support")
radv: add some infrastructure for fresh forks for each secure compile
In the following commits we want to be able to fork an existing lightweight
fork created at device creation time. In order for the user facing process
to communicate with this new fresh fork we create some members here to hold
FIFO file descriptors and a unique id.
Here we also add a new fork enum that we use to tell the lightweight
process to create a fresh fork.
For more information on why we create a fresh fork see the following
commits.
This fixes a build failure on MSVC.
BTW, it looks like clang supports _Pragma() but I don't know if it
understands the "gcc unroll N" directive.

gitlab-ci: update deqp build so we can generate xml
Update the deqp build to preserve testlog-to-xml and stylesheets, so
deqp runner can extract .qpa for failed/flaked tests, and convert to
xml. With this, will be able to browse output from failed tests
directly from the artifacts.
The main motiviation is to give better visibility into what happens with
flaked tests, when it is difficult/impossible to reproduce the flake
locally (ie. when it happens once out of N million tests). But this
should also make it easier to debug regressions that a MR triggers,
especially when it is on hw that you don't have.
