    [turbofan] Unwind and jump to the catch handler in the deoptimizer. · ab3b3bec

    The idea here is to perform the handler lookup in the deoptimizer, and then take the information from the handler table to build the catch handler frame in the deoptimizer. Specifically, we use the pc offset, context location and stack height (in full-code) to tweak the output frame.
    
    Sadly, this still requires nasty voodoo for the liveness analyzer so that it keeps variables alive if they are used in the catch handler.
