Some special-case code paths in order.go didn't expect OCALLFUNC to have Ninit; in particular, OAS2FUNC and ODEFER/OGO failed to call o.init on their child OCALLFUNC node. This resulted in not all of the AST being properly ordered. This was noticed because order is responsible for introducing an invariant around how OAPPEND is used, which is enforced by walk. However, there were perhaps simpler cases (e.g., simple order of evaluation) that were being silently miscompiled. Fixes #31010.
