> @jayfoad, can you link to the documentation where these new registers are described? Preferably from a comment in the top of the file(s). It would make it easier to review for correctness.

ISA documentation will be linked from https://llvm.org/docs/AMDGPUUsage.html#additional-documentation when it is made public.
