    x86: Remove unnecessary vex.w check for xh_mode in disassembler
    
    For all the xh_mode usage in table, they are all using %XH, which will
    print "{bad}" while EVEX.W=1. This makes this vex.w check unnecessary.
    
    opcodes/ChangeLog:
    
            * i386-dis.c (OP_E_memory): Remove vex.w check for xh_mode.
