    vect: Reject non-byte offsets for gather/scatters [PR107346]

    The ada failure reported in the PR was being caused by
vect_check_gather_scatter
    failing to deal with bit offsets that weren't multiples of BITS_PER_UNI=
T.
This
    patch makes vect_check_gather_scatter reject memory accesses with such
offsets.

    gcc/ChangeLog:

            PR tree-optimization/107346
            * tree-vect-data-refs.cc (vect_check_gather_scatter): Reject
offsets
            that aren't multiples of BITS_PER_UNIT.=
