target/s390x: Improve cc computation for ADD LOGICAL
The resulting cc is only dependent on the result and the carry-out. So save those things rather than the inputs. Carry-out for 64-bit inputs is had via tcg_gen_add2_i64 directly into cc_src. Carry-out for 32-bit inputs is had via extraction from a normal 64-bit add (with zero-extended inputs).
