IPA ICF: enhance dump about items in a non-singular class. 

2019-06-10  Martin Liska  <mliska@suse.cz>

	* ipa-icf.c (sem_item_optimizer::parse_nonsingleton_classes):
	Update coding style.
	(sem_item_optimizer::dump_cong_classes):
	Print how many items are in a non-singular class.  Improve
	coding style.
