Unrolled build for rust-lang#120204

Rollup merge of rust-lang#120204 - azhogin:azhogin/collapse_debuginfo_for_builtin, r=petrochenkov

Builtin macros effectively have implicit #[collapse_debuginfo(yes)]

If collapse_debuginfo attribute for builtin macro is not specified explicitly, it will be effectively set to `#[collapse_debuginfo(yes)]`.
