[Mesa-dev] [PATCH 2/2] radv: reset the image's predicate after a color decompression pass

[Samuel Pitoiset]

After performing a fast-clear eliminate, a FMASK decompress,
or a DCC decompress, we can reset the predicate to FALSE.

With that, the GPU should be able to skip unnecessary color
decompression passes.
