* tree-vectorizer.h (vectorizable_condition): Add argument.
        * tree-vect-loop.c (vectorizable_reduction): Fail for condition
        in SLP.  Update calls to vectorizable_condition.
        * tree-vect-stmts.c (vect_is_simple_cond): Add basic block info
        to the arguments.  Pass it to vect_is_simple_use_1.
        (vectorizable_condition): Add slp_node to the arguments.
        Support vectorization of basic blocks.  Fail for reduction in
        SLP.  Update calls to vect_is_simple_cond and
        vect_is_simple_use.  Support SLP: call vect_get_slp_defs to get
        vector operands.
        (vect_analyze_stmt): Update calls to vectorizable_condition.
        (vect_transform_stmt): Likewise.
        * tree-vect-slp.c (vect_create_new_slp_node): Handle COND_EXPR.
        (vect_get_and_check_slp_defs): Handle COND_EXPR.  Allow pattern
        def stmts.
        (vect_build_slp_tree): Handle COND_EXPR.
        (vect_analyze_slp_instance): Push pattern statements to root
        node.
        (vect_get_constant_vectors): Fix comments.  Handle COND_EXPR.
