Implement -fopt-info support for IPA ICF.

2019-08-09  Martin Liska  <mliska@suse.cz>

	* ipa-icf.c (sem_function::merge): Define AUTO_DUMP_SCOPE and
	use dump_printf to report optimization.
	(sem_variable::merge): Likwise.
	(sem_item_optimizer::merge_classes): Use dump_printf to report
	ICF hits.
2019-08-09  Martin Liska  <mliska@suse.cz>
