The code for collecting and storing data for the TraceGen0Time and TraceGen1Time output is very convoluted. It is difficult to follow the code, some unnecessary updates are done and there is unused code.

Also, we don't need the separation between ParallelGCThreads=0 and ParallelGCThreads >= 1. The relevant data is still present.
