    [Vect] Fix mask check on Scatter loads/stores

    Previously, IFN_MASK_SCATTER_STORE was used if 'loop_masks' was
    non-null, but the mask used is 'final_mask'. This caused a bug where
    a 'MASK_STORE' was vectorized into a 'SCATTER_STORE' instead of a
    'MASK_SCATTER_STORE'. This fixes PR target/99102.

    gcc/ChangeLog:

            PR target/99102
            * tree-vect-stmts.c (vectorizable_store): Fix scatter store mask
            check condition.
            (vectorizable_load): Fix gather load mask check condition.
