* cgraph.c (cgraph_same_body_alias_1, cgraph_same_body_alias,
cgraph_add_thunk): Add node pointers.
* lto-cgraph.c (lto_output_node): Verify that thunks&aliases are
associated to right node.
(input_node): Update use of cgraph_same_body_alias
and cgraph_add_thunk.
* optimize.c (maybe_clone_body): Update call of cgraph_same_body_alias
and cgraph_add_thunk.
