panfrost: LogicOp support
The generated shaders are definitely not optimal, but for a feature
hardly anyone uses, it's probably good enough.
The XScreensaver demos quasicrystal, blitspin, bouboule, crystal and
munch now seem to work, with no obvious problems.
Currently this only works for 8-bit textures.
