LGTM with CI passing.

I know it exists in the other benchmarks, but we don't have to continue this tradition.

To be precise, `sortable` -> `strict_weak_order` -> `relation` -> `predicate` is the chain to follow for this information from https://en.cppreference.com/w/cpp/iterator/sortable.

Ignore my comment. It's true that cv-ref qualified versions have to compare the same way, but it's not guaranteed that the comparator has to accept a `const` version.

> `sort` doesn't perform a well-defined number of operations. Do you mean a test that checks that the number of comparisons is less than `N log(N)`? I'm not sure it's meaningful for a small `N`. Do we have any precedent for that? I don't see this being tested for the non-ranges version of `sort`. There are some complexity tests for the ranges algorithms, but all those that I remember were linear.

I think the are also a few that aren't linear, but we never check complexity requirements for algorithms with big-O notation complexity.

Most of the slower ones are within 15-20% of the classic version, but some are 2.5-3 times slower (e.g. `BM_Sort_string_SingleElement_16384`). I don't see any obvious pattern and also no reason for the ranges version to outperform the non-ranges version -- either I'm doing something wrong, or these benchmarks contain too much random variation to do a meaningful comparison.

This convinced me that there is too much variation between different runs, so I quickly hacked together a combined benchmark which runs the classic and the ranges versions right after each other for each input.

> > The results are a lot more reasonable: most are within 5% and almost all are within 10%, with just 2 outliers (`BM_RangesSort_float_Ascending_16384_Ranges` is 13.86% slower in the ranges version, and `BM_RangesSort_float_Descending_1_Ranges` is 25.73% faster in the ranges version). The outliers follow each other in quick succession, leading me to believe both of them are part of some random fluctuation in CPU load. Moreover, the ranges version outperforms the classic version more often than the other way round (though I don't see a reason for it and presume it's not meaningful).

> Note: I tried changing the order so that the ranges version goes before the classic version, thinking that perhaps caching gives the latter of the two an advantage. However, the results are comparable, the ranges version still seems to have a slight edge on average.
The problem were the external instantiations. Removing them let the numbers look more expected:
