Sorting Algorithm Benchmarks C# .NET Core 3

I benchmarked (using benchmarkdotnet) some of the common sorting algorithms in C# .NET Core 3.0. If you use generic arguments + structs to pass in the comparison function, you can achieve faster custom sorting than than the provided Array.Sort<T>(T[], Comparison<T>) or Array.Sort<T>(T[], IComparer<T>) methods in the .NET libraries. I didn't even replicate the sorting algorithm, but the base Quick and Merge sort algorithms were already faster than the aforementioned .NET methods for at least N ~ 10000 when you use structs (I only benchmarked up to 10000 so far). The source code is available if you want to run the benchmark yourself.

• The XXXRunTime benchmarks use runtime delegates for their compare functions.
• The XXXCompileTime benchmarks use structs for their compare functions (so there is no delegate at runtime).
• The SystemArraySort benchmark is the System.Array.Sort method. Note: the System.Array.Sort method does not allow custom sorting while all other benchmarked methods do.
• The SystemArraySortDelegate benchmark is the System.Array.Sort<T>(T[], System.Comparison<T>) method, where System.Comparison<T> is a runtime delegate.
• The SystemArraySortIComparer benchmark is the System.Array.Sort<T>(T[], System.Collections.Generic.IComparer<T>) method.
