SymbolWrapper.cpp doesn't use std::optional or llvm::Optional, so this
patch removes the extraneous include. Note that llvm/ADT/Optional.h
has been deprecated upstream. This patch ensures that
SymbolWrapper.cpp continues to compile even after the upcoming removal
of Optional.h.
Do not implement HashStable for HashSet (MCP 533)
This PR removes all occurrences of `HashSet` in query results, replacing it either with `FxIndexSet` or with `UnordSet`, and then removes the `HashStable` implementation of `HashSet`. This is part of implementing [MCP 533](https://github.com/rust-lang/compiler-team/issues/533), that is, removing the `HashStable` implementations of all collection types with unstable iteration order.
The changes are mostly mechanical. The only place where additional sorting is happening is in Miri's override implementation of the `exported_symbols` query.

After removing the `map_in_place` method, which isn't much use because
modifying every element in a collection such as a `Vec` can be done
trivially with iteration.
Account for binders correctly when adding default RPITIT method assumption
As of #108203, we install extra projection predicates into the param-env of a default trait method when it has return-position `impl Trait` (or is async).
The implementation didn't account for the fact that it's walking into and out of binders, so we just need to shift all the debruijn indices accordingly when constructing the projection predicates.
Fixes#108579
r? types
Add a new config flag, dist.include-mingw-linker.
The flag controls whether to copy the linker, DLLs, and various libraries from MinGW into the rustc toolchain.
It applies only when the host or target is pc-windows-gnu.
The flag is true by default to preserve existing behavior.
Make `rustc_query_system` take `QueryConfig` by instance.
This allows for easy switching between virtual tables and specialized instances for queries. It also has the benefit of less turbofish. `QueryStorage` has also been merged with `QueryCache`.

Update askama to 0.12 and improve whitespace control
`askama` 0.12 was just released, and it adds the possibility to have "whitespace suppression" enabled by default in the configuration so I switched to it.

feat: impl better help for `.poll()` not found on `impl Future`
Partially address #108572
I'd like to also address suggestions for generalized `Self` parameters as well. That'll be a separate PR.
Remove the option to disable `llvm-version-check`
We don't support old versions of LLVM; there's no reason to have an easy way to force bootstrap to use them anyway. If someone really needs to use an unsupported version, they can modify bootstrap to change the version range.
r? ``@cuviper`` on whether we want to do this or not, since you maintain rust on Fedora and touched this config last.
Add `collection_is_never_read`
Fixes#9267
`@flip1995` and `@llogiq,` I talked with you about this one at Rust Nation in London last week. :-)
This is my first contribution to Clippy, so lots of feedback would be greatly appreciated.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`
`dogfood` found one true positive (see #9509) and no false positives.
`lintcheck` found no (true or false) positives, even when running on an extended set of crates.
