    IBM Z: Remove redundant V_HW_64 mode iterator.
    
    gcc/ChangeLog:
    
            * config/s390/vector.md (V_HW_64): Remove mode iterator.
            (*vec_load_pair<mode>): Use V_HW_2 instead of V_HW_64.
            * config/s390/vx-builtins.md
            (vec_scatter_element<V_HW_2:mode>_SI): Use V_HW_2 instead of
            V_HW_64.
