Log:

        * tree-vect-stmts.c (vectorizable_type_demotion): Handle basic
        block vectorization.
        (vectorizable_type_promotion): Likewise.
        (vect_analyze_stmt): Call vectorizable_type_demotion and
        vectorizable_type_promotion for basic blocks.
        (supportable_widening_operation): Don't assume loop
        vectorization.
        * tree-vect-slp.c (vect_build_slp_tree): Allow multiple types
        for basic blocks.  Update vectorization factor for basic block
        vectorization.
        (vect_analyze_slp_instance): Allow multiple types for basic
        block vectorization.  Recheck unrolling factor after
        construction of SLP instance.
