	* ipa-inline-transform.c (preserve_function_body_p): Look for
	first non-thunk clone.
	(save_function_body): Save into first non-thunk.
	* lto-cgraph.c (lto_output_edge): When streaming thunk do not look
	up call stmt id.
	(lto_output_node): Inline thunks don't need body in every
	partition.
	* lto-streamer-in.c: Do not fixup thunk clones.
	* cgraphclones.c (cgraph_node::create_edge_including_clone): Skip
	thunks.
	* tree-inline.c (copy_bb): Be prepared for target node to be new after
	folding suceeds.
