Auto merge of #25778 - econoplas:master, r=pnkfelix
A regression was introduced by commit https://github.com/rust-lang/rust/commit/7b1916d25347913fce3e336517ef22025ccd875f #25612. Negative signed integer literals less than -9223372036854775808i64 were no longer properly reported as #[warn(overflowing_literals)]. Also adding missing test cases to test/compile-fail/lint-type-overflow.rs which could have detected the regression. Further explanation: The expression `(negative && v > max as u64 + 1)` relies on the fact that algebraically speaking `-min == max + 1` to avoid negation and removing the need for `min` completely. If i128 or i256 are ever added, it should also work for these types without requiring a change to `min != i64::MIN &&` also simplifying maintenance. r? @pnkfelix
