switch to try_fold and segregate the drop handling to keep
collect::<Vec<u8>>() and similar optimizer-friendly
It comes at the cost of less accurate debug_asserts and code complexity
Convert many files to intra-doc links

I recommend reviewing one commit at a time, but the diff is small enough you can do it all at once if you like :)
Applied `#![deny(unsafe_op_in_unsafe_fn)]` in library/std/src/wasi
partial fix for #73904
There are still more that was not applied in [mod.rs]( 38fab2ea92/library/std/src/sys/wasi/mod.rs) and that is due to its using files from `../unsupported`
like:
```
#[path = "../unsupported/cmath.rs"]
pub mod cmath;
```

- Fix a small typo. (rust-lang/edition-guide#218)
inliner: Avoid query cycles when optimizing generators
The HIR Id trick is insufficient to prevent query cycles when optimizing
generators, since merely requesting a layout of a generator also
computes its `optimized_mir`.
Make no attempts to inline functions into generators within the same
crate to avoid query cycles.
Fixes#76181.
Fix typos in vec try_reserve(_exact) docs
`try_reserve` and `try_reserve_exact` docs refer to calling `reserve` and `reserve_exact`.
`try_reserve_exact` example uses `try_reserve` method instead of `try_reserve_exact`.
Move to intra-doc links for library/core/src/iter/traits/iterator.rs
Helps with #75080.
@jyn514 We're almost finished with this issue. Thanks for mentoring. If you have other topics to work on just let me know, I will be around in Discord.

* Link from `core` to `std` (#74481):
[`OsStr`]
[`String`]
[`VecDeque<T>`]
Rename and expose LoopState as ControlFlow
Basic PR for #75744. Addresses everything there except for documentation; lots of examples are probably a good idea.
Make all methods of `std::net::Ipv4Addr` const
Make the following methods of `std::net::Ipv4Addr` unstable const under the `const_ipv4` feature:
- `octets`
- `is_loopback`
- `is_private`
- `is_link_local`
- `is_global` (unstable)
- `is_shared` (unstable)
- `is_ietf_protocol_assignment` (unstable)
- `is_benchmarking` (unstable)
- `is_reserved` (unstable)
- `is_multicast`
- `is_broadcast`
- `is_documentation`
- `to_ipv6_compatible`
- `to_ipv6_mapped`
This would make all methods of `Ipv6Addr` const.
Of these methods, `is_global`, `is_broadcast`, `to_ipv6_compatible`, and `to_ipv6_mapped` require a change in implementation.
Part of #76205
