Add coverage to continue statements
`continue` statements were missing coverage. This was particularly
noticeable in a match pattern that contained only a `continue`
statement, leaving the branch appear uncounted. This PR addresses the
problem and adds tests to prove it.

When encountering a E0382 borrow error involving an `Option` or `Result`
provide a suggestion to use `.as_ref()` on the prior move location to
avoid the move.
Fix#84165.

* Remove `prefix` param of `document_short/full`, `render_markdown`, as its always an empty string.
* Remove `Option` wrapping of `document_short` `parent`, as its always `Some`.
Rustdoc doesn't work on IE11. It's been broken for months, it isn't supported
by the [tiered browser support list], it's even more severely broken on other
Rust websites, and IE11 doesn't support the `<details>` tag that we want
to use.
In the interest of honesty, let's give an actual error message for anyone
on IE11.

Remove unused footer section
I realized yesterday while working on docs.rs that rustdoc was generating a "footer"section that it doesn't use. No need to keep it then.

Introduce CompileMonoItem DepNode
This is likely required for allowing efficient hot code swap support in cg_clif's jit mode. My prototype currently requires re-compiling all functions, which is both slow and uses a lot of memory as there is not support for freeing the memory used by replaced functions yet.

Match against attribute name when validating attributes
Extract attribute name once and match it against symbols that are being
validated, instead of using `Session::check_name` for each symbol
individually.
Assume that all validated attributes are used, instead of marking them
as such, since the attribute check should be exhaustive.
Instead of creating a JS toggle, this injects details/summary for
sub-variants of enums. This also fixes the CSS so that the toggle button
does not jump when expanding/collapsing.
rustdoc: Reduce visual weight of attributes.
Followup from #83337. As part of that PR, we stopped hiding attributes behind a toggle, because most things have just zero or one attributes. However, this made clear that the current rendering of attributes emphasizes them a lot, which distracts from function signatures. This PR changes their color of attributes to be the same as the toggles, and reduces their font weight.
This also removes `#[lang]` from the list of ALLOWED_ATTRIBUTES. This attribute is an implementation detail rather than part of the public-facing documentation.
Demo at https://hoffman-andrews.com/rust/de-emph-attr/std/string/struct.String.html#method.trim
The `[+]` in the upper right of a rustdoc page expands or collapses all
toggles on the page. That state is stored across page loads, but is used
inconsistently. This change explicitly stops storing or using the state.
un-double `return` on try_err
This fixes#7103 by looking at the parent expression and omitting the "return " in the suggestion when its already a `return` expression.
