tree-vect-analyze.c (vect_build_slp_tree): Return false if vectype cannot be determined for the scalar type.

	* tree-vect-analyze.c (vect_build_slp_tree): Return false if
	vectype cannot be determined for the scalar type.
	(vect_analyze_slp_instance): Likewise.
	* tree-vect-transform.c (vect_model_reduction_cost): Change the
	return type to bool. Return false if vectype cannot be determined
	for the scalar type.
	(vect_get_constant_vectors): Return false if vectype cannot be
	determined for the scalar type.
	(get_initial_def_for_induction, vect_get_vec_def_for_operand,
	get_initial_def_for_reduction, vect_create_epilog_for_reduction,
