Log message:
	* tree.def (REDUC_MAX_EXPR, REDUC_MIN_EXPR, REDUC_PLUS_EXPR): New
	tree-codes.
	* optabs.h (OTI_reduc_smax, OTI_reduc_umax, OTI_reduc_smin,
	OTI_reduc_umin, OTI_reduc_plus): New optabs for reduction.
	(reduc_smax_optab, reduc_umax_optab, reduc_smin_optab, reduc_umin_optab,
	reduc_plus_optab): New optabs for reduction.
	* expr.c (expand_expr_real_1): Handle new tree-codes.
	* tree-inline.c (estimate_num_insns_1): Handle new tree-codes.
	* tree-pretty-print.c (dump_generic_node, op_prio, op_symbol): Handle
	new tree-codes.
	* optabs.c (optab_for_tree_code): Handle new tree-codes.
	(init_optabs): Initialize new optabs.
	* genopinit.c (optabs): Define handlers for new optabs.
	
	* tree-vect-analyze.c (vect_analyze_operations): Fail vectorization in
	case of a phi that is marked as relevant. Call vectorizable_reduction.
	(vect_mark_relevant): Phis may be marked as relevant.
	(vect_mark_stmts_to_be_vectorized): The use corresponding to the
	reduction variable in a reduction stmt does not mark its defining phi
	as relevant. Update documentation accordingly.
	(vect_can_advance_ivs_p): Skip reduction phis.
	* tree-vect-transform.c (vect_get_vec_def_for_operand): Takes
	additional argument. Handle reduction.
	(vect_create_destination_var): Update call to vect_get_new_vect_var.
	Handle non-vector argument.
	(get_initial_def_for_reduction): New function.
	(vect_create_epilog_for_reduction): New function.
	(vectorizable_reduction): New function.
	(vect_get_new_vect_var): Handle new vect_var_kind.
	(vectorizable_assignment, vectorizable_operation, vectorizable_store,
	vectorizable_condition): Update call to vect_get_new_vect_var.
	(vect_transform_stmt): Call vectorizable_reduction.
	(vect_update_ivs_after_vectorizer): Skip reduction phis.
	(vect_transform_loop): Skip if stmt is both not relevant and not live.
	* tree-vectorizer.c (reduction_code_for_scalar_code): New function.
	(vect_is_simple_reduction): Was empty - added implementation.
	* tree-vectorizer.h (vect_scalar_var): New enum vect_var_kind value.
	(reduc_vec_info_type): New enum vect_def_type value.
	* config/rs6000/altivec.md (reduc_smax_v4si, reduc_smax_v4sf,
	reduc_umax_v4si, reduc_smin_v4si, reduc_umin_v4sf, reduc_smin_v4sf,
	reduc_plus_v4si, reduc_plus_v4sf): New define_expands.
	
	* tree-vect-analyze.c (vect_determine_vectorization_factor): Remove
	ENABLE_CHECKING around gcc_assert.
	* tree-vect-transform.c (vect_do_peeling_for_loop_bound,
	(vect_do_peeling_for_alignment, vect_transform_loop,
	vect_get_vec_def_for_operand): Likewise.
