Review comment:
Note that the main point of difference is whether we treat a node as graph
node or normal one. the current semantics on the TIR is to treat expr nodes as
normal nodes. We could change the definition by marking all TIR expr as graph
nodes as well(if we decided to do so later), which will give the other behavior.
