I'd probably abstain from explicitly deleting what is already implicitly
deleted, but otherwise this looks good to me. Thanks!

Comment at: clang/include/clang/Sema/Sema.h:1790
SemaDiagnosticBuilder(const SemaDiagnosticBuilder &) = default;
+ SemaDiagnosticBuilder &operator=(const SemaDiagnosticBuilder &) = delete;
~SemaDiagnosticBuilder();

Being explicit is certainly a good thing, but the C++ committee wants to go
into the direction of "copy/move operations are implicitly deleted if any of
them or the destructor is user-declared." See
[depr.impldec](https://eel.is/c++draft/depr.impldec). It is already partially
the case, for example here. So why do need to spell something out explicitly
when the language goes into the direction of being even more implicit?
