    Document cond_copysign and cond_len_copysign optabs [PR112951]
    
    This adds the documentation for cond_copysign and cond_len_copysign optabs.
    Also reorders the optabs.def to be in the similar order as how the internal
    function was done.
    
    gcc/ChangeLog:
    
            PR middle-end/112951
            * doc/md.texi (cond_copysign): Document.
            (cond_len_copysign): Likewise.
            * optabs.def: Reorder cond_copysign to be before
            cond_fmin. Likewise for cond_len_copysign.
