Log message:
	* tree-vect-analyze.c (vect_analyze_operations): Fail vectorization
	in case of a relevant phi.
	(vect_analyze_data_ref_dependence): Check if distance modulo VF is
	zero. Check if absolute distance is greater than 0. Updated debug
	printouts accordingly.
	(vect_mark_relevant): Phis may be marked as relevant.
	(vect_mark_stmts_to_be_vectorized): Last use of a reduction does not
	mark its defining phi as relevant. Update documentation accordingly.
	(vect_pattern_recog_1): Remove setting of STMT_VINFO_EXTERNAL_USE.
	(vect_can_advance_ivs_p): Skip reduction phis.
	* tree-vect-transform.c (vect_get_vec_def_for_operand): Takes
	additional argument. Reduction is handled inside the switch. Return a
	vector def instead of a scalar def for reduction by calling
	get_initial_def_for_reduction. The scalar_def is returned in the new
	argument.
	(vectorizable_target_reduction_pattern, vectorizable_reduction)
	(vectorizable_assignment, vectorizable_operation, vectorizable_store)
	(vectorizable_select): Update call to vect_get_vec_def_for_operand.
	(get_initial_def_for_reduction): Last argument changed from bool* to
	tree*. Second argument name changed to init_val. Move ADJUST_IN_EPILOG
	ifdefs.
	(vect_create_epilog_for_reduction): Update call to
	vect_get_vec_def_for_operand. Call to get_initial_def_for_reduction
	moved to vect_get_vec_def_for_operand. Remove ifdef ADJUST_IN_EPILOG.
	Remove use of STMT_VINFO_EXTERNAL_USE, find immediate uses instead.
	(vect_update_ivs_after_vectorizer): Skip reduction phis.
	* tree-vectorizer.h (after_loop_use): Field removed from stmt_vec_info.
	(STMT_VINFO_EXTERNAL_USE): Macro removed.
	
	* tree-vect-analyze.c (vect_determine_vectorization_factor)
	(vect_analyze_operations, vect_enhance_data_refs_alignment)
	(vect_stmt_relevant_p): Remove ENABLE_CHECKING guard around gcc_assert.
	* tree-vect-transform (vect_finish_stmt_generation)
	(vectorizable_reduction, vectorizable_target_reduction_pattern)
	(vectorizable_target_reduction_pattern, vectorizable_assignment)
	(vectorizable_operation, vectorizable_select, vect_transform_loop)
	(vect_do_peeling_for_loop_bound, vect_do_peeling_for_alignment): Remove
	ENABLE_CHECKING guard around gcc_assert.
	(vect_create_cond_for_align_checks): Replace an abort with a gcc_assert.
	* tree-vectorizer.c (slpeel_update_phi_nodes_for_guard1)
	(new_stmt_vec_info): Remove setting of STMT_VINFO_EXTERNAL_USE.
	(vect_is_simple_use): Update documentation.
	(reduction_code_for_scalar_code): Update documentation. Swap operands
	if needed.
	* tree-vect-transform.c (vect_get_new_vect_var): Remove redundant code.
	* tree.def: Fix typo.
