Jan Beulich 36938cabf0 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.
