target-ppc: Fix narrow-mode add/sub carry output
Broken in b5a73f8d8a57e940f9bbeb399a9e47897522ee9a, the carry itself was fixed in 79482e5ab38a05ca8869040b0d8b8f451f16ff62. But we still need to produce the full 64-bit addition. Simplify the conditions at the top of the functions for when we need a new temporary. Only plain addition is important enough to warrent avoiding the temporary, and the extra tcg move op that would come with it.
