Update bench for 2020

[fendor]

Not sure if something like this is wanted anymore, but I repeated the benchmarks out of curiosity and thought, maybe it is interesting.

Basic benchmark information:

Compiler: GHC 8.8.3
Run: stack bench :time && ./Report.hs out.csv
RAM: 32GB (4*8GB) DDR4 3600 MT/s
CPU: AMD Ryzen 7 3800X 8-Core Processor

Thanks.

I think it's hard to tell what this is benchmarking without a stack.yaml update. An lts-resolver would tell people what GHC version and what versions of each package is being tested.

As it stands, your submitted PR shows that for some unknown package versions for an undocumented GHC, these are some results.

If you were running a stack bench :time, you would expect to see basically the same ratios with respect to eachother. If your machine was 10x faster, the numbers would be smaller, but they'd all still show the same proportions to one another like they do from my laptop. If the packages have been modified for better performance, you'd see different proportions, but as it stands we don't know what those packages are for sure.

If you want to try with stack on the current resolver and then try on a latest resolver that uses GHC 8.8.3, I'd be interested to see the difference in numbers.

Better late than never, right? Finally found the time to re-run the benchmarks with stack.

Looks good!
