ir3: Add cat5/cat7 cache related instructions and cat7 sleep

Danylo Piliaiev requested to merge Danil/mesa:feature/ir3/new-cache-instructions into main
  • tcinv - Likely Texture Cache Invalidate (unverified)
  • icinv - Mostly sure that it is Instruction Cache Invalidate
  • dccln - Data Cache Clean
  • dcinv - Data Cache Invalidate
  • dcflu - Data Cache Flush
  • sleep - Has short and long variants, long seem to be ~20 times longer. The exact difference between it and a bunch of nops is unknown.

The emission of these instructions were not observed in the wild.

I was only able to get observable results from testing icinv and sleep.

TODO: find out the difference between .shr and .all modes of dccln, dcinv, dcflu.

I don't have a practical usage for them at the moment. Maybe they could be useful for some debug mode, or even in shader debugging...
