@shafik: Since this is a generated file, it is very easy to regenerate after a revert with `python3 clang/www/make_cxx_dr_status && git commit -am '[Clang][NFC] Update cxx_dr_status.html'`

@Endilll: I've removed the other changes from `cxx_dr_status.html` manually from this commit. Can you create the separate patch to add the new cwg issues? Thanks!
