[x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understand

Browse Source 
It seems there is no separate instruction class for having AdSize *and*
OpSize bits set, which is required in order to disambiguate between all
these instructions. So add that to the disassembler.

Hm, perhaps we do need an AdSize16 bit after all?
