Jan Beulich 4102be5cf9 x86: replace EXxmm_mdq by EXVexWdqScalar 
There's no need to have two operand specifiers / enumerators for the
same purpose. This then renders xmm_mdq_mode unused.

Jan Beulich cd546e7bd2 x86: add missing pseudo ops for VPCLMULQDQ ISA extension 
While the ISA extensions doc suggests them to be made available just
like the SDM does for the PCLMULQDQ ISA extension, these weren't added
when supposrt for the new extension was introduced.

Also make sure the 64-bit non-AVX512 test actually tests VEX encodings,
not EVEX ones.

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.)
