…marks, r=KodrAus introduce benchmarks of BTreeSet.intersection 16 tests combining 4 kinds of contents with different sizes exposing edge cases. The ones with asymmetric sizes are addressed by rust-lang#58577. The pos_vs_neg cases seems (are were meant to be) the same as the neg_vs_pos case (same thing, reverse order) but reality shows a surprsing 25% difference.
