PPC: [interpreter] Heal closures when bytecode array is gone.

PPC: [interpreter] Heal closures when bytecode array is gone.

Port 5c8609de9d597000fdb92dffe954d7ed994488b2

Original commit message:

    This ensures the InterpreterEntryTrampoline heals code entry fields
    inside closures when being called without a valid bytecode array. This
    is preparatory work to allow removal of bytecode when switching some
    functions to other types of code.
