IPA ICF: target and optimization flags comparison.

	* cgraphunit.c (cgraph_node::create_wrapper): Fix level of indentation.
	* ipa-icf.c (sem_function::equals_private): Add support for target and
	(sem_item_optimizer::merge_classes): Remove redundant function
	optimization flags comparison.
	* tree.h (target_opts_for_fn): New function.
	* gcc.dg/ipa/ipa-icf-32.c: New test.
