    tree-optimization/96978 - fix fallout of BB vectorization of live stmts

    This avoids looking at STMT_VINFO_LIVE_P when vectorizing BBs.

            * tree-vect-stmts.c (vectorizable_condition): Do not
            look at STMT_VINFO_LIVE_P for BB vectorization.
            (vectorizable_comparison): Likewise.
