    radeonsi: Decompress DCC textures in a render feedback loop.
    
    By using a counter to quickly reject textures that are not
    bound to a framebuffer, the performance impact when binding
    sampler_views/images is not too large.

Unreal elemental mis-renders metalwork.

Working with current mesa/llvm.

Not sure when/what fixed as I haven't tested for a while.
