#112865 with the tidy exemptions and tracing and syn 2 not upgraded
Additional deps:
equivalent: indexmap
errno: through rustix
errno-dragonfly: errno
nu-ansi-term: tracing
overload: nu-ansi-term
r? Mark-Simulacrum
There's currently a deadlock with tracing when RUSTC_LOG is enabled.
Downgrade tracing-core for now to avoid blocking the other updates.
syns upgrades cause some nontrivial changes in the diagnostics derive tests,
which are best dealt with in another PR.
Add `-Zremark-dir` unstable flag to write LLVM optimization remarks to YAML
This PR adds an option for `rustc` to emit LLVM optimization remarks to a set of YAML files, which can then be digested by existing tools, like https://github.com/OfekShilon/optview2. When `-Cremark-dir` is passed, and remarks are enabled (`-Cremark=all`), the remarks will be now written to the specified directory, **instead** of being printed to standard error output. The files are named based on the CGU from which they are being generated.
Currently, the remarks are written using the LLVM streaming machinery, directly in the diagnostics handler. It seemed easier than going back to Rust and then form there back to C++ to use the streamer from the diagnostics handler. But there are many ways to implement this, of course, so I'm open to suggestions :)
I included some comments with questions into the code. Also, I'm not sure how to test this.

Don't pass --test-args to `python -m unitest`
The args for unittest and cargo test are mutually incompatible. Suggest that people use `python -m unittest ...` manually instead.
This also changes `bootstrap_test.py` to be easier to run standalone; see the commit for details.

Fix `dropping_copy_types` lint from linting in match-arm with side-effects
This PR fixes an issue with the `dropping_copy_types` and `dropping_references` lints when not all patterns that can have side-effects were detected and ignored.
Nearly _fixes_ https://github.com/rust-lang/rust/issues/112653 (will need beta-backport to completely fix the issue)

Make simd_shuffle_indices use valtrees
This removes the second-to-last user of the `destructure_mir_constant` query. So in a follow-up we can remove the query and just move the query provider function directly into pretty printing (which is the last user).
cc `@rust-lang/clippy` there's a small functional change, but I think it is correct?
Implement most of MCP510
This implements most of what remains to be done for MCP510:
- turns `-C link-self-contained` into a `+`/`-` list of components, like `-C link-self-contained=+linker,+crto,+libc,+unwind,+sanitizers,+mingw`. The scaffolding is present for all these expected components to be implemented and stabilized in the future on their own time. This PR only handles the `-Zgcc-ld=lld` subset of these link-self-contained components as `-Clink-self-contained=+linker`
- handles `-C link-self-contained=y|n` as-is today, for compatibility with `rustc_codegen_ssa:🔙🔗:self_contained`'s [explicit opt-in and opt-out](9eee230cd0/compiler/rustc_codegen_ssa/src/back/link.rs (L1671-L1676)).
- therefore supports our plan to opt out of `rust-lld` (when it's enabled by default) even for current `-Clink-self-contained` users, with e.g. `-Clink-self-contained -Clink-self-contained=-linker`
- turns `add_gcc_ld_path` into its expected final form, by using the `-C link-self-contained=+linker` CLI flag, and whether the `LinkerFlavor` has the expected `Cc::Yes` and `Lld::Yes` shape (this is not yet the case in practice for any CLI linker flavor)
- makes the [new clean linker flavors](https://github.com/rust-lang/rust/pull/96827#issuecomment-1208441595) selectable in the CLI in addition to the legacy ones, in order to opt-in to using `cc` and `lld` to emulate `-Zgcc-ld=lld`
- ensure the new `-C link-self-contained` components, and `-C linker-flavor`s are unstable, and require `-Z unstable-options` to be used
The up-to-date set of flags for the future stable CLI version of `-Zgcc-ld=lld` is currently: `-Clink-self-contained=+linker -Clinker-flavor=gnu-lld-cc -Zunstable-options`.
It's possible we'll also need to do something for distros that don't ship `rust-lld`, but maybe there are already no tool search paths to be added to `cc` in this situation anyways.

Shrink error variants for layout and fn_abi
The errors are bigger than the result, so let's put them behind a reference. Since query results have to be `Copy`, we use a reference into the arena instead of a `Box<T>`.
The args for unittest and cargo test are mutually incompatible. Suggest that people use `python -m unittest ...` manually instead.
This also changes `bootstrap_test.py` to be easier to run standalone; see the commit for details.

Fix try builds on the msvc builder
Try builds have been optimized to build less components, however bootstrap was still expecting them to be present on msvc. This PR (extracted from https://github.com/rust-lang/rust/pull/112267) fixes that.

Error when RPITITs' hidden types capture more lifetimes than their trait definitions
This implements a stricter set of captures rules for RPITITs. They now may only capture:
1. Lifetimes from the impl header (both the self type and any trait substs -- we may want to restrict just to the self type's lifetimes, but the PR makes that easy to do, too)
2. Lifetimes mentioned by the `impl Trait` in the trait method's definition.
Namely, they may not mention lifetimes from the method (early or late) that are not mentioned in the `impl Trait`.
cc #105258 which I think was trying to do this too, though I'm not super familiar with what exactly differs from that or why that one was broken.
cc #112194 (doesn't fix this issue per se, because it's still an open question, but I think this is objectively better than the status quo, and gets us closer to resolving that issue.)
Technically is a fix for the ICE in #108580, but it turns that issue into an error now. We can decide separately whether or not nested RPITITs should capture lifetimes from their parents.

fix(resolve): skip assertion judgment when NonModule is dummy
Fixes#85992
## Why #85992 panic
During `resolve_imports`, the `path_res` of the import `issue_85992_extern_2::Outcome` is pointing to `external::issue_85992_extern_2` instead of `crate::issue_85992_extern_2`. As a result `import.imported_module.set` had been executed.
Attached 1: the state of `early_resolve_ident_in_lexical_scope` during the `resolve_imports` for `use issue_85992_extern_2::Outcome` is as follows:
|iter in `visit_scopes` | `scope` | `result.binding` |
| - | - | - |
| init | - | - |
| 0 | `CrateRoot` | Err(Determined) |
| 1 | `ExternPrelude` | pointing to the `issue_85992_extern_2`(external) |
However, during finalization for `issue_85992_extern_2::Outcome`, the `innermost_result` was pointed to `crate::issue_85992_extern_2` and no ambiguity was generated, leading to a panic.
Attached 2: the state of `early_resolve_ident_in_lexical_scope` during the `finalize_import` for `use issue_85992_extern_2::Outcome` is as follows:
|iter in `visit_scopes` | `scope` | `result.binding` | `innermost_result` |
| - | - | - | - |
| init | - | - | `None` |
| 0 | `CrateRoot` | pointing to `use crate::issue_85992_extern_2` **(introdcued by dummy)** | same as `result` but with a `Some` wapper|
| 1 | `ExternPrelude` | pointing to the `issue_85992_extern_2`(external) | smae as above |
