    aarch64: Expand maximum number of operands from 5 to 6
    
    Given the introduction of the new Armv9.4-a `sysp' insn using the
    following syntax:
    
            sysp #<op1>, <Cn>, <Cm>, #<op2>{, <Xt1>, <Xt2>}
    
    and by extension the need to encode 6 assembly operands, extend
    Binutils to handle instructions taking 6 operands, up from a previous
    maximum of 5.
