    [TypeFeedbackVector] special ic slots for interpreter compare/binary ops. · b88d132f
    mvstanton authored
    Full code uses patching ICs for this feedback, and the interpreter uses
    the type feedback vector. It's a good idea to code the vector slots
    appropriately as ICs so that the runtime profiler can better gauge if
    the function is ready for tiering up from Ignition to TurboFan.
    
    As is, the feedback is stored in "general" slots which can't be
    characterized by the runtime profiler into feedback states.
    
    This CL addresses that problem. Note that it's also important to
    carefully exclude these slots from the profiler's consideration when
    determining if you want to optimize from Full code.
