Looking at the clang-tidy changes only, this looks good. Though, I don't know if the changes to Clang are okay with Clang maintainers, but maybe they have an untapped use for this as well? Either way, a Clang maintainer needs to sign off on those changes before merging. Maybe there are also different ideas on how to detect overflow
