x86: drop dqa_mode
I assume this mode was needed when EVEX.W handling wasn't really correct yet for other than 64-bit mode. It's clearly not needed anymore. Its elimination also allows dropping the EVEX.W split of VCVT{,U}SI2SS. (For the record, the dropped mode would have been wrong if used in any table entry not already guaranteeing EVEX.W=1.)
