Fix the instruction table entries for AI1_adde_sube_s_irs multiclass definition so that
all the instruction have:
let Inst{31-27} = 0b1110; // non-predicated
Before, the ARM decoder was confusing:
> 0x40 0xf3 0xb8 0x80
as:
Opcode=16 Name=ADCSSrs Format=ARM_FORMAT_DPSOREGFRM(5)

adcs pc, r8, r0, asr #6
since the cond field for ADCSSrs is a wild card, and so is ADCrs, with the ADCSSrs having Inst{20} as '1'.
Now, the AR decoder behaves correctly:
> 0x40 0xf3 0xb8 0x80
> END
