Benchmarking DotNetCore 2.1, 2.2,3.0 and CLR 4.7.2

Following Stephen Toub post from April 2018 on DotNetCore 2.0 and 2.1 benchmarks, I have decided to update it with latest DotNetCore3.0 preview. Most of the following are taken from his post. The benchmarking library is benchmarkdotnet.

Experimental setup

All benchmarks were run on the same computer (Dell XPS 9550, in flight mode, antivirus off):
