Auto merge of #59445 - alexreg:ban-multi-trait-objects-via-aliases, r=oli-obk
Ban multi-trait objects via trait aliases Obviously, multi-trait objects are not normally supported, so they should not be supported via trait aliases. This has been factored out from the previous PR https://github.com/rust-lang/rust/pull/55994 (see point 1). r? @Centril CC @nikomatsakis ------------------ ### RELNOTES: We now allow `dyn Send + fmt::Debug` with equivalent semantics to `dyn fmt::Debug + Send`. That is, the order of the mentioned traits does not matter wrt. principal/not-principal traits. This is a small change that might deserve a mention in the blog post because it is a language change but most likely not. See https://github.com/rust-lang/rust/blob/ce2ee305f9165c037ecddddb5792588a15ff6c37/src/test/ui/traits/wf-trait-object-reverse-order.rs. // @Centril
