c4b18c689f radv: Emit compressed primitive nodes on GFX12
Some checks are pending

Emits two triangles per node whenever possible. The nir code will
revisit the triangle node to handle the second triangle only if both
triangles are interescted by the ray.

df44b353ad radv: Optimize ray tracing position fetch
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Gets rid of a lot of indirection when fetching triangle positions.
Storing the primitive address increases register pressure by a bit but
the traversal shader which should have the highest register demand
should not be affected when position fetch is not used.
