Jan Beulich 36cc073ef4 x86: remove ModRM.mod decoding layer from AVX512F VMOVS{S,D} 
Just like their AVX counterparts they can utilize XMVexScalar /
EXdVexScalarS / EXqVexScalarS taking care of dropping the middle operand
for their memory forms.

H.J. Lu e395f487b3 i386: Check vector length for scatter/gather prefetch instructions 
Since not all vector lengths are supported by scatter/gather prefetch
instructions, decode them only with supported vector lengths.

Jan Beulich 54fbadc0c3 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.)
