No longer parse it.

type error method suggestions use whitelisted identity-like conversions
Previously, on a type mismatch (and if this wasn't preëmpted by a
higher-priority suggestion), we would look for argumentless methods
returning the expected type, and list them in a `help` note. This had two
major shortcomings: firstly, a lot of the suggestions didn't really make
sense (if you used a &str where a String was expected,
`.to_ascii_uppercase()` is probably not the solution you were hoping
for). Secondly, we weren't generating suggestions from the most useful
traits! We address the first problem with an internal
`#[rustc_conversion_suggestion]` attribute meant to mark methods that keep
the "same value" in the relevant sense, just converting the type. We
address the second problem by making `FnCtxt.probe_for_return_type` pass
the `ProbeScope::AllTraits` to `probe_op`: this would seem to be safe
because grep reveals no other callers of `probe_for_return_type`.
Also, structured suggestions are pretty and good for RLS and friends.
Unfortunately, the trait probing is still not all one would hope for: at a
minimum, we don't know how to rule out `into()` in cases where it wouldn't
actually work, and we don't know how to rule in `.to_owned()` where it
would. Issues #46459 and #46460 have been filed and are ref'd in a FIXME.
This is hoped to resolve #42929, #44672, and #45777.

Fix examples of Duration::subsec_millis and Duration::subsec_micros
Update examples of `Duration::subsec_millis` and `Duration::subsec_micros`, because they are not for these two methods actually.

Fix docs for OsStr
At present, there are two small issues with the [docs](https://doc.rust-lang.org/std/ffi/struct.OsStr.html) for std::ffi::OsStr:
- The docs say "OsStr is to OsString as String is to &str: the former in each pair are borrowed references; the latter are owned strings.". The latter pair is mixed up: String is the owned variant whereas &str is the borrowed reference.
- The doc links to String and &str are broken and render as [String] and [&str].
This PR fixes these issues.

the `ProbeScope::AllTraits` to `probe_op`: this would seem to be safe
because grep reveals no other callers of `probe_for_return_type`.
Also, structured suggestions are preferred (because they're pretty, but
also for RLS and friends).
Also also, we make the E0055 autoderef recursion limit error use the
one-time-diagnostics set, because we can potentially hit the limit a lot
during probing. (Without this,
test/ui/did_you_mean/recursion_limit_deref.rs would report "aborting due to
51 errors").
Unfortunately, the trait probing is still not all one would hope for: at a
minimum, we don't know how to rule out `into()` in cases where it wouldn't
actually work, and we don't know how to rule in `.to_owned()` where it
would. Issues #46459 and #46460 have been filed and are ref'd in a FIXME.

Bump to 1.25.0
* Bump the release version to 1.25
* Bump the bootstrap compiler to the recent beta
* Allow using unstable rustdoc features on beta - this fix has been applied to
the beta branch but needed to go to the master branch as well.

[unix] Don't clone command-line args on startup
Fixes part of #47164 and simplifies the `args` code on non-Apple Unix platforms.
Note: This could change behavior for programs that use both `std::env::args` *and* unsafe code that mutates `argv` directly. However, these programs already behave differently on different platforms. The new behavior on non-Apple platforms is closer to the existing behavior on Apple platforms.

Minor rewrite of env::current_exe docs; clarify symlinks.
- Update example in ‘security’ section to use hard links, like the
linked securityvulns.com example.
- Weaken language on symbolic links – indicate behavior is
platform-specific

Correct a few stability attributes
* The extra impls for `ManuallyDrop` were added in #44310 which was only stabilised in 1.22.0.
* The impls for `SliceIndex` were stabilised in #43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable.
* The `From` impls for atomic integers were added in #45610 but most atomic integers are still unstable.
* The `shared_from_slice2` impls were added in #45990 but they won't be stable until 1.24.0.
* The `Mutex` and `RwLock` impls were added in #46082 but won't be stable until 1.24.0.

Link against -lunwind on CloudABI.
CloudABI makes use of LLVM's libunwind to do stack unwinding. It is
installed under the name libunwind.a.
|

Don't attempt to build libunwind on CloudABI, as libunwind is already
provided by the system by default.
