This rather crucial requirement was not checked. In most cases, that didn't cause any trouble because the argument types are required to outlive the call and are subtypes of a subformula of the callee type. However, binary ops are taken by ref only indirectly, without it being marked in the argument types, which led to the argument types not being constrained anywhere causing spurious errors (as these are basically unconstrainable, I don't think this change can break code). Of course, the old way was also incorrent with contravariance, but that is still unsound for other reasons. This also improves rustc::front to get RUST_LOG to *somewhat* work. Fixes #28999
