    Debugger: use debug break slot to break on call. · 8965b683
    yangguo authored
    Break point at calls are currently set via IC. To change this, we
    need to set debug break slots instead. We also need to distinguish
    those debug break slots as calls to support step-in.
    
    To implement this, we add a data field to debug break reloc info to
    indicate non-call debug breaks or in case of call debug breaks, the
    number of arguments. We can later use this to find the callee on the
    evaluation stack in Debug::PrepareStep.
