Don't time `emit_ignored_resolution_errors`
This printed several hundred lines each time rustdoc was run, almost all
of which rounded to 0.000. Since this isn't useful info, don't print it
everywhere, so other perf info is easier to read.

Use `summary_opts()` in another spot
I added `summary_opts()` before I cut the branch for #77686 (2 months
ago!), so this "slipped through the cracks".
Validate naked functions definitions
Validate that naked functions are defined in terms of a single inline assembly
block that uses only `const` and `sym` operands and has `noreturn` option.
Implemented as future incompatibility lint with intention to migrate it into
hard error. When it becomes a hard error it will ensure that naked functions are
either unsafe or contain an unsafe block around the inline assembly. It will
guarantee that naked functions do not reference functions parameters (obsoleting
part of existing checks from #79411). It will limit the definitions of naked
functions to what can be reliably supported. It will also reject naked functions
implemented using legacy LLVM style assembly since it cannot satisfy those
conditions.

Update Clippy
Biweekly Clippy update (which I forgot about on Thursday)
This includes a `Cargo.lock` update, so probably needs `rollup=never`.
r? `@Manishearth`
extend `WithOptConstParam` docs, move rustdoc test
This should hopefully make things a bit clearer, feel free to comment on anything which can still be improved.

Update RLS and Rustfmt
Fixes#79406Fixes#79407
This does pull 1.4.28 version of Rustfmt. Do you want me to pull the 1.4.29 while we're at it?

A slightly clearer diagnostic when misusing const
Fixes#79598
This produces the following diagnostic:
"expected one of `>`, a const expression, lifetime, or type, found keyword `const`"
Instead of the previous, more confusing:
"expected one of `>`, const, lifetime, or type, found keyword `const`"
This might not be completely clear as some users might not understand what a const expression is, but I do believe this is an improvement.
Fix src/test/ui/env-vars.rs on 128-core machines on Windows
On Windows, the environment variable NUMBER_OF_PROCESSORS has special
meaning. Unfortunately, you can get different answers, depending on
whether you are enumerating all environment variables or querying a
specific variable. This was causing the src/test/ui/env-vars.rs test
to fail on machines with more than 64 processors when run on Windows.
check the recursion limit when finding a struct's tail
fixes#79437
This does a `delay_span_bug` (via `ty_error_with_message`) rather than emit a new error message, under the assumption that there will be an error elsewhere (even if the type isn't infinitely recursive, just deeper than the recursion limit, this appears to be the case).
Coverage tests for remaining TerminatorKinds and async, improve Assert
Tested and validate results for panic unwind, panic abort, assert!()
macro, TerminatorKind::Assert (for example, numeric overflow), and
async/await.
Implemented a previous documented idea to change Assert handling to be
the same as FalseUnwind and Goto, so it doesn't get its own
BasicCoverageBlock anymore. This changed a couple of coverage regions,
but I validated those changes are not any worse than the prior results,
and probably help assure some consistency (even if some people might
disagree with how the code region is consistently computed).
Fixed issue with async/await. AggregateKind::Generator needs to be
handled like AggregateKind::Closure; coverage span for the outer async
function should not "cover" the async body, which is actually executed
in a separate "closure" MIR.
Use `item_name` instead of pretty printing for resolving `Self` on intra-doc links
Pretty printing would add a `r#` prefix to raw identifiers, which was
not correct. In general I think this change makes sense -
pretty-printing is for showing to the *user*, `item_name` is suitable to
pass to resolve.

The span was unused.

Render Markdown in search results
Fixes#32040.
Previously Markdown documentation was not rendered to HTML for search results,
which led to the output not being very readable, particularly for inline code.
This PR fixes that by rendering Markdown to HTML with the help of pulldown-cmark
(the library rustdoc uses to parse Markdown for the main text of documentation).
However, the text for the title attribute (the text shown when you hover over an
element) still uses the plain-text rendering since it is displayed in browsers
as plain-text.
Only these styles will be rendered; everything else is stripped away:
* *italics*
* **bold**
* `inline code`
