https://github.com/Endilll created https://github.com/llvm/llvm-project/pull/121642
This patch brings our C++ DR status page up to date with WG21 updates.
[CWG1223](https://cplusplus.github.io/CWG/issues/1223.html) "Syntactic disambiguation and _trailing-return-types_" is resolved by [P2915R0](https://wg21.link/p2915r0) "Proposed resolution for CWG1223". Both the test and the paper were written by @cor3ntin, so I presume no updates are needed.
[CWG2819](https://cplusplus.github.io/CWG/issues/2819.html) "Cast from null pointer value in a constant expression" was revisited and marked as not a DR, so I updated the test to ensure that the example is not accepted in C++23 and earlier modes. CC @offsetof.
Tentantive resolutions to the following issues were simply promoted to actual resolutions, so tests doesn't require any meaningful changes:
- [CWG2913](https://cplusplus.github.io/CWG/issues/2913.html) "Grammar for deduction-guide has requires-clause in the wrong position" (@zyn0217)
- [CWG2915](https://cplusplus.github.io/CWG/issues/2915.html) "Explicit object parameters of type void" (@MitalAshok)
- [CWG2922](https://cplusplus.github.io/CWG/issues/2922.html) "constexpr placement-new is too permissive" (@cor3ntin)
As a drive-by fix, I updated the `make_cxx_dr_status` script to accommodate for `C++23 onwards` and `C++26 onwards` statuses, which are useful for Core issues that are not DRs.
