stdio: Document no support for writing to non-blocking stdio/stderr
Printing to stdio/stderr that have been opened with non-blocking
(O_NONBLOCK in linux) can result in an error, which is not handled
by std::io module causing a panic.

Add -api-level to pm command
As of ~Aug 30th, `pm build` commands require an `api-level` flag. This flag should match the fuchsia api-level that's being targeted by the code. Since this is dependent on the version of the SDK that's being used, we may want to change this to something a bit more robust in the future.
Open a BCrypt algorithm handle
Fixes#101474, supplants #101456.
Replaces use of a pseduo handle with manually opening a algorithm handle.
Most interesting thing here is the atomics.

This rule was added in 4e2c59a970
to benefit the module items table. However, the module items table stopped
using table tags when 6020c79dde
switched us over to grid layout.
You can see when this one used to be triggered by visiting
<https://doc.rust-lang.org/1.54.0/alloc/slice/index.html#structs-1> in a
very narrow window, but it doesn't any more, because the module table is
now rendered using `<div>` tags.
This selector has its roots in these commits:
* current version:
`.content .methods > div:not(.notable-traits):not(.method)` from
9077d540da
* intermediate version:
`.content .methods > div:not(.important-traits)` from
d86621f69e
* original version:
`.content .methods > div { margin-left: 40px; }` from
0a46933c4d
Based on the call stack, where [`class='methods'`] calls `trait_item` and
[`trait_item`] calls [`document`], this div selector was probably intended to
target docblock and stability tags.
In the current version of the code, neither of these can possibly be nested
directly below the `class='methods'` wrapper, because the [current version of
the `trait_item` function] always wraps them in a `<details>` tag if they
exist. The only div tag that can possibly be nested directly below it now is
the one with class `method`, which is explicitly excluded.
[`class='methods'`]: 0a46933c4d/src/librustdoc/html/render.rs (L1811-L1842)
[`trait_item`]: 0a46933c4d/src/librustdoc/html/render.rs (L1807)
[`document`]: 0a46933c4d/src/librustdoc/html/render.rs (L1515-L1523)

now that CI correctly detects rust-lld in run-make tests, we ignore this
test since it relies on `-Zgcc-ld=lld` which is not made to work on the
windows-msvc targets: it requires a gcc flavor.
Track PGO profiles in depinfo
This PR makes sure that PGO profiles (`-Cprofile-use` and `-Cprofile-sample-use`) are tracked in depinfo, so that when they change, the compilation session will be invalidated.
This approach was discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/246057-t-cargo/topic/Tracking.20PGO.20profile.20files.20in.20cargo).
I tried it locally and it seems that the code is recompiled just with this change, and https://github.com/rust-lang/rust/pull/100413 is not even needed. But it's possible that not everything required is recompiled, so we will probably want to land both changes.
Another approach to implement this could be to store the PGO profiles in `sess.parse_sess.file_depinfo` when the session is being created, but then the paths would have to be converted to a string and then to a symbol, which seemed unnecessarily complicated.

- Add a `HandleCycleError` enum to rustc_query_system, along with a `handle_cycle_error` function
- Move `Value` to rustc_query_system, so `handle_cycle_error` can use it
- Move the `Value` impls from rustc_query_impl to rustc_middle. This is necessary due to orphan rules.
Suggest `unwrap_or_default` when closure returns `"".to_string`
Closes https://github.com/rust-lang/rust-clippy/issues/9420
changelog: [`unwrap_or_else_default`]: suggest `unwrap_or_default()` instead of `unwrap_or_else` with a closure that returns an empty `to_string`.
rustdoc: remove unused CSS `#results > table`
This code was added in 96ef2f8ab9 to improve rendering of the search results table, but results have not used a table since b615c0c854 switched it to rendering with `<div>` tags.
