The first split left unit-regression2.cpp 0.7% below the size develop links at, which the comparison change in the follow-up immediately used up: the MinGW linker fails on test-regression2_cpp20 again, naming copy_shallow and to_partial_ordering among the relocations it cannot fit. Move the sections from "issue #2067" on, and the helper types they use, so that the file stops being the one that decides whether the tests can be linked at all. At -O0 and C++20, unit-regression2.cpp is now 2,964,944 bytes against develop's 4,708,248, and 3,070,568 bytes with the follow-up applied - roughly a third smaller either way, rather than a fraction of a percent larger. The 135 assertions are the same ones as before, now spread over three test cases in two files. Also silence the clang-tidy findings the deep-nesting tests draw: the copies they make are what is being tested, and the reserve() computation gets its parentheses.
