ACO got a lot better at forming VOPD instructions, and testing
feedback seems to point in a slightly positive direction for this.
gfx12 will also start requiring wave32 for dynamic VGPR allocation at
some point.

Implement a mitigation for VM faults caused by SMEM reading
from NULL descriptors.
In order to satisfy VKD3D-Proton's expectations on mutable
descriptors, we must do this in shader code, it is not
sufficient to use the address of a mapped BO when writing
null descriptors. It is not feasible to mitigate this
in VKD3D-Proton.

RADV_PERFTEST=sparse is a new option to enable experimental
support for sparse features when they aren't enabled by default:
- gfx6 supports sparse, albeit with a reduced feature set
- gfx7 supports 3D images (with non-standard block shape)
and unaligned mip sizes
- gfx8 supports the same feature set as gfx7
(Polaris behaves more stable than other gfx8, so we had
already enabled it by default on Polaris for a long time.)
We pass all dEQP-VK.*sparse* tests on gfx6-8 when running on
a single thread however it may cause hangs or failures
when executing the tests on multiple parallel jobs.
We plan to enable this by default when we deem it stable enough.
Until then, users can already test some games that use it.
Note, at the moment there are some unsolved problems in the
amdgpu kernel driver regarding sparse bindings on these GPUs.

vkd3d-proton (DX12) and Zink (GL) have always been enabling features
that require the global BO list to be enabled.
Since DXVK 2.7+ (August 2025), it's also always enabled by default for
DX9-11 games (because it requires BDA now).
The global BO list used to decrease performance in the past mostly
because of bad memory management in AMDGPU, but it seems the situation
slightly improved since. Though, there might still some workloads that
hit the issue, but I think it should be mostly good overall.
This introduces RADV_DEBUG=nobolist to disable the global BO list
when no features require it.

The option creates a buffer where each bit stores whether the
corresponding 4096 byte memory section has been allocated. The helper
radv_build_is_valid_va allows for querying the validity of addresses
inside a nir shader which can be useful for debugging.

This exposes an experimental implementation of HIC with
RADV_PERFTEST=hic. It's passing 100% of VKCTS but it requires some
benchmarks first to verify if performance is acceptable or not.
