PR ipa/89684
	* multiple_target.c (create_dispatcher_calls): Change
	references_to_redirect from vector of ipa_ref * to vector of ipa_ref.
	In the node->iterate_referring loop, push *ref rather than ref, call
	ref->remove_reference () and always pass 0 to iterate_referring.

	* gcc.target/i386/pr89684.c: New test.
