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.

When the scratch ringbuffer settings are changed, the shader unit has
to be idle or we will have shaders using old and new settings.
That combination is not supported on the HW (likely the offset is
ringbuffer idx * WAVESIZE * 1024).

This extension allows to use subgroup operations with 8 and 16-bits
Untested on GFX6-GFX7, and most of subgroup operations are broken
on GFX10, so don't enable it for now. Not enabled on ACO because
it's still doesn't support 8-bits/16-bits.

This extension adds the device coherent and device uncached memory
types. It's known to be slower than non-device coherent memory but
it might be useful for debugging.
This is only exposed for chips that support L2 uncached.

This actually supports more of the extension than the LLVM backend but we
can't enable it because ACO doesn't work with all stages yet.
With more of it enabled, some CTS tests fail because our 64-bit sqrt
is very imprecise. I can't find any precision requirements for it
anywhere, so I'm thinking it might be a CTS issue.

This extension allows to control the subgroup size by allowing a
varying subgroup size and also specifying a required subgroup size.
This implementation only allows to specify a required subgroup
size for compute shaders because there is some caveats with
other shader stages (eg. NGG with geometry shader). This
basically allows apps to use Wave32 for compute shaders.
This extension is enabled for all chips but only GFX10 supports
Wave32. ACO doesn't support it.

This is actually a non-threaded implementation. I'd summarize this
as event-based submission.
When submit happens we walk a tree of submissions that depend on
the syncobj signal operations to be submitted and if those submission
we no other dependencies we start to execute them immediately.
Or, well I still use a list to avoid issues with long chains and
the stacksize when using recursion.

This does not fully do wait-before-submit, to be done in a follow

Can be enabled via the environment variable which tells the
driver how many compilation threads are expected to be called,
and therefore how many forked processes the driver should
create.

This can be usefull for debugging the on disk cache, but is also
useful in the following patch for secure compiles which will be
used to compile huge pipeline collections. These pipeline
collections can be multiple GBs and the in memory cache grows to
multiple GBs very quickly when they are compiled so we want to
be able to turn off the in memory cache.

This exposes what's required for DX and this is what we already
configure. The driver flushes denorms for FP32 and preserves them
for FP16/FP64. Note that we can't allow both preserving and
flushing denorms because this won't work for merged shaders. This
will require LLVM to update the float mode register to make it work.
Only enabled on GFX8+ with the LLVM path because it's untested on
previous chips and ACO doesn't support it.
