Jan Beulich 04d824a468 x86: disambiguate disassembly of certain AVX512 insns
Certain conversion operations as well as vfpclassp{d,s} are ambiguous
when the input operand is in memory and no broadcast is being used.
While in Intel mode this gets resolved by printing suitable operand
size modifiers, AT&T mode need mnemonic suffixes to be added.
