        * config/rs6000/rs6000.c (get_vector_offset): New helper function
        to calculate the offset in memory from the start of a vector of a
        particular element.  Add code to keep the element number in
        bounds if the element number is variable.
        (rs6000_adjust_vec_address): Move calculation of offset of the
        vector element to get_vector_offset.
        (rs6000_split_vec_extract_var): Do not do the initial AND of
        element here, move the code to get_vector_offset.

    Fix PR 93568 (thinko)
