Frame Construction markers take so much time for marker allocation

Currently we have both markers and profiling labels for frame construction. But in a Slack conversation, jesup said that the profiler_tracing method takes over %10 of time in the frame constructions and he can't take a very long sample of Speedometer without it taking forever to load the profile. It's because there are so many ContentAppended/Removed markers in the profile. We should remove the markers and keep the profiling labels instead. See the profiles: http://bit.ly/2N2Dhjj http://bit.ly/2N6OWhj
Markers are taking so much time(~10%) to allocate and in a website like Speedometer, it takes ages to load the profile data since there are so many frame construction markers.
