Subject: tree-ssa-loop-niter.c (record_estimate): Use GGC_NEW to allocate
 struct nb_iter_bound.

	* tree-ssa-loop-niter.c (record_estimate): Use GGC_NEW to allocate
	struct nb_iter_bound.
	(free_numbers_of_iterations_estimates_loop): Use ggc_free.
	* gengtype.c (open_base_files): Add cfhloop.h to the list of includes.
	* cfgloopmanip.c (place_new_loop): Vector larray is gc-allocated.
	* tree-scalar-evolution.c: Include gt-tree-scalar-evolution.h.
	(struct scev_info_str, scalar_evolution_info): Add GTY markers.
	(new_scev_info_str): Use GGC_NEW to allocate struct scev_info_str.
	(del_scev_info): Use ggc_free.
	(scev_initialize): Allocate scalar_evolution_info in gc memory.
	* loop-init.c: Include ggc.h.
	(loop_optimizer_init): Use GGC_CNEW to allocate struct loops.
	(loop_optimizer_finalize): Use ggc_free.
	* tree-ssa-loop.c (pass_tree_unswitch, pass_vectorize,
	pass_linear_transfom, pass_empty_loop, pass_complete_unroll,
	pass_iv_optimize): Add TODO_ggc_collect.
	* function.h (struct function): Remove skip marker from x_current_loops.
	* cfgloop.c: Include ggc.h.
	(flow_loops_free, flow_loop_free): Free the loop descriptions in gc
	memory.
	(establish_preds): Vector superloops is gc allocated.
	(alloc_loop): Allocate loop using GGC_CNEW.  Allocate head of
	loop->exits list.
	(flow_loops_find): Vector larray is gc allocated.
	(loop_exit_free): Use ggc_free.
	(rescan_loop_exit): Use GGC_NEW to allocate struct loop_exit.  Reflect
	that head of exits list is now not a part of struct loop.
	(record_loop_exits): Allocate exits table in gc memory.
	(get_loop_exit_edges, verify_loop_structure, single_exit): Reflect that
	head of exits list is now not a part of struct loop.
	* cfgloop.h (struct lpt_decision, struct nb_iter_bound,
	struct loop_exit): Add GTY marker.
	(struct loop): Add GTY marker.  Make superloops vector gc allocated.
	Add skip marker to aux field.  Make head of exits list a separate
	object.
	(struct loops): Add GTY marker.  Make larray vector gc allocated.
	Add param marker to exits table.
	(get_loops): Type changed.
	* Makefile.in (tree-scalar-evolution.o): Add gt-tree-scalar-evolution.h
	dependency.
	(cfgloop.o, loop-init.o): Add ggc.h dependency.
	(GTFILES): Add cfgloop.h and tree-scalar-evolution.c.
	* basic-block.h (struct basic_block_def): Remove skip marker from
	loop_father field.
