Rollup merge of #130914 - compiler-errors:insignificant-dtor, r=Amanieu
Mark some more types as having insignificant dtor These were caught by https://github.com/rust-lang/rust/pull/129864#issuecomment-2376658407, which is implementing a lint for some changes in drop order for temporaries in tail expressions. Specifically, the destructors of `CString` and the bitpacked repr for `std::io::Error` are insignificant insofar as they don't have side-effects on things like locking or synchronization; they just free memory. See some discussion on #89144 for what makes a drop impl "significant"
