Currently, when copying definition node of an inlined var, we do not update var Defn field to point to new copied node. That causes all inlined vars point to the same Defn, and ir.StaticValue can not find inlined var in the lhs of its definition. clovar creates new ONAME node for local variables or params of closure inside inlined function, by copying most of the old node fields. So the new Node.Defn is not modified, its lhs still refer to old node instead of new one. To fix this, we need to do two things: - In subst.clovar, set a dummy Defn node for inlvar - During subst.node, when seeing OAS/OAS2 nodes, after substituting, we check if any node in lhs has the dummy Defn, then set it to the current OAS/OAS2 node.
