The rust compiler not only outputs symbols in the form that C++ does, but it also mangle symbols like '&' and '~' to special compiler-defined escape sequences. For convenience, these symbols are demangled when printing backtraces.
This commit goes back to using `gensym` to generate unique tokens to put into the names of closures, allowing closures to be able to get demangled in backtraces. Closes rust-lang#12400

Add some more infrastructure support for demangling `$`-sequences, as well as fixing demangling of closure symbol names if there's more than one closure in a function.

Deprecate `maybe_misused_cfg` and `mismatched_target_os` All cases that these two lints would catch are now caught by cargo/rustc's own check-cfg feature. This was previously discussed on zulip: https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Deprecate.20maybe_misused_cfg.20and.20mismatched_target_os For the most part, this PR was automated with `cargo dev deprecate` r? `@flip1995` cc `@Urgau` changelog: deprecate [`maybe_misused_cfg`] and [`mismatched_target_os`]
