Implement rust-lang/compiler-team#578.
When an ICE is encountered on nightly releases, the new rustc panic
handler will also write the contents of the backtrace to disk. If any
`delay_span_bug`s are encountered, their backtrace is also added to the
file. The platform and rustc version will also be collected.

Fixes #110111
This bug, and the workaround in this commit, is closely linked to
[raphlinus/pulldown-cmark#441], getting offsets of link
components. In particular, pulldown-cmark doesn't provide the
offsets of the contents of a link.
To work around this, rustdoc parser parts of a link definition
itself.

update `pulldown-cmark` to `0.9.3`
This PR updates `pulldown-cmark` to version `0.9.3`, which does two main things:
* Pulls in https://github.com/raphlinus/pulldown-cmark/pull/643 to fix https://github.com/rust-lang/rust/issues/111117
* Allows parsing strikethrough with single tildes, e.g. `~foo~` -> ~foo~. This matches the [GFM spec](https://github.github.com/gfm/#strikethrough-extension-).

This test case currently fails on s390x, and probably other
platforms where the last line of a backtrace does not contain
and " at <source location>" specification.
The problem with the existing normalization lines
// normalize-stderr-test "\s*\d{1,}: .*\n" -> ""
// normalize-stderr-test "\s at .*\n" -> ""
is that \s matches all whitespace, including newlines, so the
first (but not second) of these regexes may merge multiple
lines. Thus the output differs depending on which of these
matches on the last line of a backtrace.
As the whitespace used in backtraces is just normal space
characters, change both regexes to just match at least one
space character instead:
// normalize-stderr-test " +\d{1,}: .*\n" -> ""
// normalize-stderr-test " + at .*\n" -> ""

Make the BUG_REPORT_URL configurable by tools
This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy
the entire hook implementation.
I haven't changed clippy in case they want to make the change upstream instead of the subtree, but
I'm happy to do so here if the maintainers want - cc ````@rust-lang/clippy````
Fixes https://github.com/rust-lang/rust/issues/109486.

- Switch clippy to the new hook
This also adds a `extra_info` callback so clippy can include its own version number, which differs
from rustc's.
- Call `install_ice_hook` in rustfmt

rustdoc: catch and don't blow up on impl Trait cycles
Fixes #110629
An odd feature of Rust is that `Foo` is invalid, but `Bar` is okay:
type Foo<'a, 'b> = Box<dyn PartialEq<Foo<'a, 'b>>>;
type Bar<'a, 'b> = impl PartialEq<Bar<'a, 'b>>;
To get it right, track every time rustdoc descends into a type alias, so if it shows up twice, it can be write the path instead of infinitely expanding it.

Move most rustdoc-ui tests into subdirectories
This makes it easier to know where to add a new test, and makes the top-level directory less overwhelming.

Improve tests for #110138
These should live in rustdoc-json, not rustdoc-ui, so we can run assertions, and not just check there's no ICE

rustdoc: Fix invalid handling of nested items with `--document-private-items`
Fixes #110422.
The problem is that only impl block and re-exported `macro_rules!` items are "visible" as nested items. This PR adds the missing checks to handle this correctly.

The order in which the multiple errors for the ambiguous intra doc links
are printed is different.

Extend -Cdebuginfo with new options and named aliases
This is a rebase of https://github.com/rust-lang/rust/pull/83947, along with my best guess at what the new options mean. I tried to follow the LLVM source code to get a better idea but ran into quite a lot of trouble (https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/go-to-definition.20in.20src.2Fllvm-project.3F). The description for the original PR follows below.
Note that the changes in this PR have already been through FCP: https://github.com/rust-lang/rust/pull/83947#issuecomment-878384979
Closes https://github.com/rust-lang/rust/pull/109311. Helps with https://github.com/rust-lang/rust/pull/104968.

The -Cdebuginfo=1 option was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for emitting line tables only was added. Additionally an option for emitting line info directives only was added, which is needed for some targets, i.e. nvptx. The debug info options should now behave similarly to clang's debug info options.

Move `doc(primitive)` future incompat warning to `invalid_doc_attributes`
Fixes #88070.
It's been a while since this was turned into a "future incompatible lint" so I think we can now turn it into a hard error without problem.

rustdoc: Fix invalid suggestions on ambiguous intra doc links v2
Fixes https://github.com/rust-lang/rust/issues/108653.
This is another approach to fixing the same issue. This time, we keep the computed information around instead of re-computing it.
Strangely enough, the order for ambiguities seem to have been changed. Not an issue but it creates a lot of diff...
So which version do you prefer?

`-Cdebuginfo=1` was never line tables only and
can't be due to backwards compatibility issues.
This was clarified and an option for line tables only
was added. Additionally an option for line info
directives only was added, which is well needed for
some targets. The debug info options should now
behave the same as clang's debug info options.
