  Log Message:
  -----------
  [Clang][PowerPC] Add __dmr2048 type and DMF crypto builtins (#157152)

Define the __dmr2048 type to represent the DMR pair introduced by the
Dense Math Facility on PowerPC, and add three Clang builtins
corresponding to DMF cryptography:

__builtin_mma_dmsha2hash
__builtin_mma_dmsha3hash
__builtin_mma_dmxxshapad

The __dmr2048 type is required for the dmsha3hash crypto builtin, and,
as withother PPC MMA and DMR types, its use is strongly restricted.
