    This CL adds the V8 debugger part of the restart frame logic as well
    as some bits for the inspector.
    
    The CL is centered around two key pieces: When the user requests a
    restart, we stash the stack frame ID (aka the stack pointer) and
    optionally the inlined frame index for optimized frames, and then
    continue execution. Once execution bubbles back into JS land,
    we throw a termination exception when a frame restart was requested.
    
    Note that the CL doesn't hook up the logic yet to CDP and the CL
    also does not the actual handling of the termination exception
    in the unwinder.
