This is a follow-up to #179674, which applies various fixes across C++ DR tests uncovered by `-verify-directives` (#179835 ). Changes here serve double duty. First, they fix actual problems found by `-verify-directives`, because I've been manually enforcing those rules manually for quite a while. Second, they show typical problems and possible solutions when you opt-in a test to use `-verify-directives`. This PR focuses on interesting cases, as partial diagnostic matches, which are trivial to fix, are fixed in boring #179674 Changes include: 1. Getting rid of instantiations at the end of TU that emit diagnostics: either trigger them earlier, or move them to a separate file 2. Reordering of `expected-error` and `expected-note` to match the order in which corresponding diagnsotics are emitted. 3. Eliminating leftover partial matches of diagnostic text 4. Removing some extension warnings, because C++ DR tests are not interested in features backported to older language modes. 5. Fix for a hilarious case of CWG413 test, which was checking for a note from a typo correction that happened in another test.
