[PATCH] D71607: [clang-tidy] Add unsigned subtraction warning, with suggestion to convert to unsigned literals.

NoQ added a comment.

Mmm, well, on second thought, no, that probably won't be sufficient. As long as we're willing to warn on containers about which we know //absolutely nothing//, we'll still have some of those false positives. And if we stop warning on such containers, the check will probably become much more quiet and much less useful. So i think this check will work best as an opt-in style/lint guideline. It might still make a bit more sense with path-sensitive analysis but we'll still have to accept the inevitable obvious false positives so it's probably not worth it.
