Feels alright to me, it's trying to explain the need for add_cases_to_X shenanigans

…wjasper match lowering: Split off `test_candidates` into several functions and improve comments The logic of `test_candidates` has three steps: pick a test, sort the candidates, and generate code for everything. So I split it off into three methods. I also ended up reworking the comments that explain the algorithm. In particular I added detailed examples. I removed the digression about rust-lang#29740 because it's no longer relevant to how the code is structured today. r? `@matthewjasper`
