	(thread_through_all_blocks): Ditto.  Assert that loops were analysed.
	* tree-ssa-loop-manip.c (rewrite_into_loop_closed_ssa,
	verify_loop_closed_ssa): Check number_of_loops instead of current_loops.
	* predict.c (tree_estimate_probability): Ditto.
	* tree-if-conv.c (main_tree_if_conversion): Ditto.
	* tree-ssa-loop-ch.c (copy_loop_headers): Ditto.
	* modulo-sched.c (sms_schedule): Ditto.
	* tree-scalar-evolution.c (scev_const_prop): Ditto.
	(scev_finalize): Do not do anything if scev analysis was not
	initialized.
	* cfgloopanal.c (mark_irreducible_loops): Do not check whether
	current_loops == NULL.
	(mark_loop_exit_edges): Check number_of_loops instead of current_loops.
	* loop-init.c (loop_optimizer_init): Do not free current_loops when
	there are no loops.
	(loop_optimizer_finalize): Assert that loops were analyzed.
	(rtl_move_loop_invariants, rtl_unswitch, rtl_unroll_and_peel_loops,
	rtl_doloop): Check number_of_loops instead of current_loops.
	* tree-ssa-loop.c (tree_loop_optimizer_init): Do not check whether
	current_loops == NULL.
	(tree_ssa_loop_init, tree_ssa_loop_im, tree_ssa_loop_unswitch,
	gate_tree_vectorize tree_linear_transform, check_data_deps,
	tree_ssa_loop_ivcanon, tree_ssa_empty_loop, tree_ssa_loop_bounds,
	tree_complete_unroll, tree_ssa_loop_prefetch, tree_ssa_loop_ivopts):
	Check number_of_loops instead of current_loops.
	(tree_ssa_loop_done): Do not check whether current_loops == NULL.
	* tree-ssa-pre.c (fini_pre): Do not take do_fre argument.  Always
	free loops if available.
	(execute_pre): Do not pass do_fre to fini_pre.
