Description copied from class: IRScope

Make version specific to scope which needs it (e.g. Closure vs non-closure).

Overrides:

allocateInterpreterContext in class IRScope

allocateInterpreterContext

public InterpreterContext allocateInterpreterContext(java.util.function.Supplier<java.util.List<Instr>> instructions,
                                                     int temporaryVariableCount,
