    PPC: [interpreter] First implementation of stack unwinding. · 637cbeeb

    Port 0b3066b8
    
    Original commit message:
        This implements a first prototype of stack unwinding for interpreted
        frames. The unwinding machinery performs a range-based lookup in the
        given handler table and potentially continues dispatching at the handler
        offset. Note that this does not yet correctly restore the context to the
        correct value when the handler is being entered.
