Section 1.4 of the Power ISA v3.0B states that both of these instructions are single-copy atomic. As we cannot (yet) issue 128-bit loads within TCG, use the generic helpers provided. Since TCG cannot (yet) return a 128-bit value, add a slot within CPUPPCState for returning the high half of a 128-bit return value. This solution is preferred to the helper assigning to architectural registers directly, as it avoids clobbering all TCG live values.
