Subject: [SG10] nodiscard updates after Cologne?

We had two changes to [[nodiscard]] in Cologne:
- P1301R4: [[nodiscard("should have a reason")]], for C++20
- P1771R1: [[nodiscard]] for constructors, as a DR
Currently, I put both under the 201907 block (
But that means we have a [retroactive] C++17 feature whose macro has a
value two years later. Is that fine? Alternatively, we could invent an
earlier value for P1771R1 that's in the C++17 timeline.
