The logic here is the same as for Send&Sync impls.

Add str::[r]split_once This is useful for quick&dirty parsing of key: value config pairs. Used a bunch in Cargo and rust-analyzer: * https://github.com/rust-lang/cargo/search?q=splitn%282&unscoped_q=splitn%282 * https://github.com/rust-analyzer/rust-analyzer/search?q=split_delim&unscoped_q=split_delim In theory, once const-generics are done, this functionality could be achieved without a dedicated method with ```rust match s.splitn(delimier, 2).collect_array::<2>() { Some([prefix, suffix]) => todo!(), None => todo!(), } ``` Even in that world, having a dedicated method seems clearer on the intention. I am not sure about naming -- this is something I've just came up with yesterday, I don't know off the top of my head analogs in other languages. If T-libs thinks this is a reasonable API to have, I'll open a tracking issue and add more thorough tests.
Fix RefUnwindSafe & UnwinsSafe impls for lazy::SyncLazy I *think* we should implement those unconditionally with respect to `F`. The user code can't observe the closure in any way, and we poison lazy if the closure itself panics. But I've never fully wrapped my head around `UnwindSafe` traits, so 🤷♂️

…acrum Enable to ping RISC-V group via triagebot We have the RISC-V group (https://github.com/rust-lang/team/blob/master/teams/risc-v.toml) but don't enable to ping on this repository (rust-lang#74813 (comment)). We don't have the instructions on the rustc-dev-guide yet but I'll create it soonish.
