    [liveedit] reimplement frame restarting. · 3f47c63d
    yangguo authored
    Previously, when restarting a frame, we would rewrite all frames
    between the debugger activation and the frame to restart to squash
    them, and replace the return address with that of a builtin to
    leave that rewritten frame, and restart the function by calling it.
    
    We now simply remember the frame to drop to, and upon returning
    from the debugger, we check whether to drop the frame, load the
    new FP, and restart the function.
