arm/translate.c: Fix adc_CC/sbc_CC implementation
commits 49b4c31efcce45ab714f286f14fa5d5173f9069d and 2de68a4900ef6eb67380b0c128abfe1976bc66e8 reworked the implementation of adc_CC and sub_CC. The new implementations (on the TCG_TARGET_HAS_add2_i32 code path) are incorrect. The new logic is: CF:NF = 0:A +/- 0:CF CF:NF = CF:A +/- 0:B The lower 32 bits of the intermediate result stored in NF needs to be passes into the second addition in place of A (s/CF:A/CF:NF): CF:NF = 0:A +/- 0:CF CF:NF = CF:NF +/- 0:B This patch fixes the issue.
