Analyze and possibly fix the problems that Stuxxnet complained about on Discord

Here is what Stuxxnet has to say about my compiler:

you've also written a log function that runs in an infinite loop if the input is close to 1
you're trying to compare sort functions written in an interpreted language to those provided by that language in its native VM
you're overfitting measurement data to come up with a completely insane formula for the comparisons of quicksort
you're using rand in c++ code
you implement custom math functions using highschool maths that just doesn't work if you want to be numerically efficient or just even get a sane result for the whole range of possible inputs.
I'm sorry, but I really don't have much confidence in your judgement calls...

G. Sliepen also has a lot of negative comments about the way I made my compiler.
