x86: drop (now) stray IsString
The need for them on the operand-less string insns has gone away with
the removal of maybe_adjust_templates() and associated logic. Since
i386_index_check() needs adjustment then anyway, take the opportunity
and also simplify it, possible again as a result of said removal (plus
the opcode template adjustments done here).
