implicit `Option`-returning doctests
This distinguishes `Option` and `Result`-returning doctests with implicit `main` method, where the former tests must end with `Some(())`.
Open question: Does this need a feature gate?

Fix linkage diagnostic so it doesn't ICE for external crates
Fix linkage diagnostic so it doesn't ICE for external crates
(As a drive-by improvement, improved the diagnostic to indicate *why* `*const T` or `*mut T` is required.)

Emit error when trying to use PGO in conjunction with unwinding on Windows.
This PR makes `rustc` emit an error when trying use PGO in conjunction with `-Cpanic=unwind` on Windows, isn't supported by LLVM yet. The error messages points to https://github.com/rust-lang/rust/issues/61002, which documents this known limitation.
Warn on bare_trait_objects by default
The `bare_trait_objects` lint is set to `warn` by default.
Most ui tests have been updated to use `dyn` to avoid creating noise in stderr files.

do not print panic message on doctest failures
This PR cleans up rustdoc test output by silently unwinding on failure instead of using `panic!`. It also improves the clarity and consistency of the output on test failure, and adds test cases for failure modes that were previously untested.
This commit fixes a ICE where struct constructors were resulting in an
ICE with const generics. Previously, a `match` in `type_of` did not have
an arm for the `DefKind::Ctor` resolutions and therefore would assume
that the type did not have generics.
Add Step::sub_usize
Required for #54054.
I'm aware that the `Step` trait needs a rework, but this still seems like a reasonable addition?
This currently doesn't compile because Chalk contains a type that implement this trait, and this is a breaking change. How can that be fixed?
tests: Centralize proc macros commonly used for testing
Many proc macros in `ui\proc-macro\auxiliary` were doing same things.
(I added a fair share of those myself.)
Now commonly used macros (empty, identity, etc) are collected in one place - `ui\proc-macro\auxiliary\test-macros.rs`.
Changes the type `mir::Mir` into `mir::Body`
Fixes part 1 of #60229 (previously attempted in #60242).
I stumbled upon the issue and it seems that the previous attempt at solving it was not merged. This is a second try more up-to-date.
The commit should have changed comments as well.

Fixing the missing import on `AggregateKind`
Remove special case for *ios* builds in run-make-fulldeps/print-target-list Makefile
Previous `TODO` comment in this file mentions [an issue that was closed](https://github.com/rust-lang/rust/issues/29812), and I was able to confirm locally that provided code in that issue no longer produces an ICE. Discussion on that issue seems to indicate this code was no longer needed as of 1.12.0.
I removed the `*ios*` branch from this `case` statement as it may cause confusion, then removed the case statement entirely as it only had a wildcard branch.
