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.
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.
