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.
The crate hash is needed:
- if debug assertions are enabled, or
- if incr. comp. is enabled, or
- if metadata is being generated, or
- if `-C instrumentation-coverage` is enabled.
This commit avoids computing the crate hash when these conditions are
all false, such as when doing a release build of a binary crate.
It uses `Option` to store the hashes when needed, rather than
computing them on demand, because some of them are needed in multiple
places and computing them on demand would make compilation slower.
The commit also removes `Owner::hash_without_bodies`. There is no
benefit to pre-computing that one, it can just be done in the normal
fashion.
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.

Partially address #108572
I'd like to also address suggestions for generalized `Self` parameters as well. That'll be a separate PR.
