rustdoc: Use `DefId(Map,Set)` instead of `FxHash(Map,Set)`
Not all uses are converted, a few cases iterating through maps/sets and requiring nontrivial changes are kept.

Enable sanitizers for s390x-linux
Include sanitizers supported by LLVM on s390x (asan, lsan, msan, tsan) in the target definition, as well as in the compiletest supported list.
Build sanitizer runtime for the target. Enable sanitizers in the CI.
Add note about absolute paths to Path::join
The note already exists on `PathBuf::push`, but I think it is good to have it on `Path::join` as well since it can cause issues if you are not careful with your input.
Implement some more predicates in the new solver
Implement a few more goals. The subtype goal specifically is important, since it's required for this code to compile:
```
fn main() {
let mut x = vec![];
x.push(1i32);
}
```
(I think we emit a subtype goal here because of coercion).
Drive-by: Also implements `--compare-mode=next-solver` -- I've been using this locally a lot to find out what works and what doesn't. I'm also happy to split this out into another PR.

Add new bootstrap members to triagebot.toml
```@ozkanonur``` if you want to be assigned to review PRs too, just post a message to this thread.
Should a `T-bootstrap` label be created, since `src/tools/tidy` is assigned to the `bootstrap` members, but labeled `A-testsuite` (and not `A-bootstrap`) ?

Re-enable building rust-analyzer on riscv64
It was disabled in #75103 due to an LLVM bug, but followup comments have
confirmed that it builds fine on Fedora with LLVM 15.

Improve the documentation of `black_box`
There don't seem to be many great resources on how `black_box` should be used, so I added some information here
llvm-wrapper: adapt for LLVM API change
No functional changes intended.
The LLVM commit e6b02214c6 added `TargetExtTyID` to the `TypeID` enum. This adapts `RustWrapper` accordingly.
Add `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` to future-incompat report
See https://github.com/rust-lang/rust/issues/79813 for a discussion of this lint. This has been warn-by-default for over a year, so adding it to the future-incompat report should help to find libraries that haven't yet updated.
Revert "Make PROC_MACRO_DERIVE_RESOLUTION_FALLBACK a hard error"
This reverts commit 7d82cadd97 aka PR #84022
I am doing this to buy us some time with respect to issue #106337 w.r.t. the 1.67 release.
To retrieve these flags rustdoc currently has to mass decode full attributes for items in the whole crate tree, so it's better to pre-compute it in advance.
This is especially for short-term performance of https://github.com/rust-lang/rust/pull/107054 because resolver cannot use memoization of query results yet.
Remap paths in UI tests by default
If you think this needs further discussions / something RFC-like, please let me know the best forum for that.
This PR runs UI tests with a remapped "src base" directory by default.
Why? Because some UI tests currently depend on the length of the absolute path to the `src/test/ui` directory. Remapping makes the tests independent of the absolute path.
The path to the source file (which is absolute on CI) is part of the type name of closures. `rustc` diagnostic output depends on the length of type names (long type names are truncated). So a long absolute path leads to long closure type names, which leads to truncation and changed diagnostics.
(I initially tried just disabling type name truncation, but that made some error messages stupid long (thousands of characters, IIRC)).
Additional changes:
* All boolean `compiletest` directives now support explicit `no-` versions to disable them.
* Adapt existing tests when necessary:
* Disable remapping for individual tests that fail with it enabled (when there's no obvious alternative fix).
* For tests that already check something remapping related switch to the new option unless we gain something significant by keeping the manual remap.

Use UnordMap and UnordSet for id collections (DefIdMap, LocalDefIdMap, etc)
This PR changes the `rustc_data_structures::define_id_collections!` macro to use `UnordMap` and `UnordSet` instead of `FxHashMap` and `FxHashSet`. This should account for a large portion of hash-maps being used in places where they can cause trouble.
The changes required are moderate but non-zero:
- In some places the collections are extracted into sorted vecs.
- There are a few instances where for-loops have been changed to extends.
~~Let's see what the performance impact is. With a bit more refactoring, we might be able to get rid of some of the additional sorting -- but the change set is already big enough. Unless there's a performance impact, I'd like to do further changes in subsequent PRs.~~
Performance does not seem to be negatively affected ([perf-run here](https://github.com/rust-lang/rust/pull/106977#issuecomment-1396776699)).
Part of [MCP 533](https://github.com/rust-lang/compiler-team/issues/533).

There is a number of APIs that answer dominance queries. Previously they
were named either "dominates" or "is_dominated_by". Consistently use the
"dominates" form.
No functional changes.

fix check macro expansion
If the only argument to `check!` is the module name I get this error:
```
error: expected expression, found `,`
--> src/tools/tidy/src/main.rs:63:42
|
57 | / macro_rules! check {
58 | | ($p:ident $(, $args:expr)* ) => {
59 | | drain_handles(&mut handles);
60 | |
... |
63 | | $p::check($($args),* , &mut flag);

... |
69 | | }
70 | | }
| |_________- in this expansion of `check!`
...
117 | check!(hey);
| ----------- in this macro invocation
```
This change makes it so commas are added only when there are `args`.
