    rs6000: Move V2DI vec_neg under power8-vector [PR105271]

    As PR105271 shows, __builtin_altivec_neg_v2di requires option
    -mpower8-vector as its pattern expansion relies on subv2di which
    has guard VECTOR_UNIT_P8_VECTOR_P (V2DImode).  This fix is to move
    the related lines for __builtin_altivec_neg_v2di to the section
    of stanza power8-vector.
