+ add 'jmp rm16' and 'call rm16' before the rm32 versions on i8086, so the

  16-bit version is picked up by default for opsize=S_NO. Previously the 386
  version was picked on i8086, but the generated code was correct, because we
  don't yet generate a 0x66 prefix for "\325", which leads to many 32-bit
  instructions not being assembled correctly with the internal asm obj writer on
  the i8086
