	PR tree-optimization/57539
	* cgraphclones.c (cgraph_clone_node): Add parameter new_inlined_to, set
	global.inlined_to of the new node to it.  All callers changed.
	* ipa-inline-transform.c (clone_inlined_nodes): New variable
	inlining_into, pass it to cgraph_clone_node.
	* ipa-prop.c (ipa_propagate_indirect_call_infos): Do not call
	ipa_free_edge_args_substructures.
	(ipa_edge_duplication_hook): Only add edges from inlined nodes to
	rdesc linked list.  Do not assert rdesc edges have inlined caller.
	Assert we have found an rdesc in the rdesc list.
