    Skip if size of bfd_vma is smaller than address size
    
    Disassembler won't work properly when size of bfd_vma is smaller than
    address size.
    
    	PR binutils/19983
    	PR binutils/19984
    	* i386-dis.c (print_insn): Return -1 if size of bfd_vma is
    	smaller than address size.
