    i386: Correct adcx suffix in disassembler

    Since 0x66 is the opcode prefix for adcx, it is wrong to use the 'S'
    prefix:

      'S' => print 'w', 'l' or 'q' if suffix_always is true

    on adcx.  Add

      'L' => print 'l' or 'q' if suffix_always is true

    replace S with L on adcx and adox.
