In browser (DevTools) mode, only non-native JS code and callbacks are reported. Also, added "(garbage collector)" entry which accumulates samples count in GC state. Trying to display "(compiler)" and "(external)" only brings confusion, because it ends up in displaying scripts code under "(compiler)" node, and DOM event handlers under "(external)" node, which looks weird.
