Log message:
	Reverted the following patch:
	
	2005-07-05  Ira Rosen  <irar@il.ibm.com>.
	
	* lambda-code.c (gcc_loop_to_lambda_loop): Call analyze_scalar_evolution
	with correct parameters.
	* tree-data-ref.c (analyze_array_indexes): Likewise.
	(analyze_indirect_ref): Likewise and check if the reference is loop
	invariant with the help of the new parameter of analyze_scalar_evolution.
	(analyze_offset_expr): Likewise.
	* tree-elim-check.c (try_eliminate_check): Call
	analyze_scalar_evolution with correct parameters.
	* tree-scalar-evolution.c (follow_ssa_edge_inner_loop_phi,
	unify_peeled_chrec, interpret_loop_phi, interpret_condition_phi,
	interpret_rhs_modify_expr): Likewise.
	(compute_scalar_evolution_in_loop): Call
	analyze_scalar_evolution_1 with correct parameters.
	(analyze_scalar_evolution_1): Add parameters to always analyze evolution
	and to decide whether it is unknown. Fix parameters of
	interpret_rhs_modify_expr and analyze_scalar_evolution_1.
	(analyze_scalar_evolution): Add parameters to always analyze evolution
	and to decide whether it is unknown. Fix parameters of
	analyze_scalar_evolution_1.
	(instantiate_parameters_1): Call analyze_scalar_evolution with correct
	parameters.
	(analyze_scalar_evolution_for_all_loop_phi_nodes): Likewise.
	* tree-scalar-evolution.h (analyze_scalar_evolution): Add parameters to
	the declaration.
	* tree-vect-analyze.c (vect_analyze_scalar_cycles): Call
	analyze_scalar_evolution with correct parameters. Skip invariant phis
	with the help of unknown_evolution.
	(vect_can_advance_ivs_p): Likewise.
	* tree-vect-transform.c (vect_get_vec_def_for_operand): Handle invariant
	phis.
	(vect_update_ivs_after_vectorizer):  Call analyze_scalar_evolution with
	correct parameters. If no evolution, it must be an unknown evolution.
	* tree-vectorizer.h (enum vect_def_type): Add vect_invariant_phi_def.
