x86: avoid attaching suffixes to unambiguous insns
...
"Unambiguous" is is in particular taking as reference the assembler,
which also accepts certain insns - despite them allowing for varying
operand size, and hence in principle being ambiguous - without any
suffix. For example, from the very beginning of the life of x86-64 I had
trouble understanding why a plain and simple RET had to be printed as
RETQ. In case someone really used the 16-bit form, RETW disambiguates
the two quite fine.

Properly display extra data/address size prefixes
...
X86 disassembler checks data and address size prefixes when displaying
instruction mnemonic and operands. For the extra data and address size
prefixes, their names depend only on the address mode, not the data and
address size prefixes. This patch changes x86 disassembler not to check
the data and address size prefix when printing extra data and address size
prefixes.
