I've confirmed with my risu test tool that sbcs/adcs are indeed
broken even with this patch applied. Patterns used:

ADC_imm A1 cond:4 0010101 s:1 rn:4 rd:4 imm:12
ADC_reg A1 cond:4 0000101 s:1 rn:4 rd:4 imm:5 type:2 0 rm:4
ADC_rsr A1 cond:4 0000101 s:1 rn:4 rd:4 rs:4 0 type:2 1 rm:4

SBC_imm A1 cond:4 0010110 s:1 rn:4 rd:4 imm:12
SBC_reg A1 cond:4 0000110 s:1 rn:4 rd:4 imm:5 type:2 0 rm:4
SBC_rsr A1 cond:4 0000110 s:1 rn:4 rd:4 rs:4 0 type:2 1 rm:4

I really must get round to implementing the record-n-replay
functionality so you can run this kind of test without ARM
hardware to hand.
