Some MIR statements and terminators have an (undocumented...) invariant
that some of their input and outputs must not overlap. This records
conflicts between locals used in these positions.
Add host triples to target lists
This PR is primarily intended to fix https://github.com/rust-lang/rustup/issues/2494, which is the second commit. That bug was introduced by #76415, and incompletely fixed by #76639. (#76639 added host triples, which gave us compilers, but missed that we also need documentation and other target-only things). However, it also removes duplicate macOS CI builders.

compare generic constants using `AbstractConst`s
This is a MVP of rust-lang/compiler-team#340. The changes in this PR should only be relevant if `feature(const_evaluatable_checked)` is enabled.
~~currently based on top of #76559, so blocked on that.~~

Change the criteria of `interior_mutable_const`
This implements my suggestion [here](https://github.com/rust-lang/rust-clippy/issues/5050#issuecomment-680310889), and so hopefully fixes#5050.
* stop linting associated types and generic type parameters
* start linting ones in trait impls
whose corresponding definitions in the traits are generic
* remove the `is_copy` check
as presumably the only purpose of it is to allow
generics with `Copy` bounds as `Freeze` is internal
and generics are no longer linted
* remove the term 'copy' from the tests
as being `Copy` no longer have meaning
---
changelog: Change the criteria of `declare_interior_mutable_const` and `borrow_interior_mutable_const` to narrow the lints to only lint things that defenitly is a interior mutable type, not potentially.
Issue 72408 nested closures exponential
This fixes#72408.
Nested closures were resulting in exponential compilation time.
This PR is enhancing asymptotic complexity, but also increasing the constant, so I would love to see perf run results.
The Rust version number is currently embedded in bootstrap's source
code, which makes it hard to update it automatically or access it
outside of ./x.py (as you'd have to parse the source code).
This commit moves the version number to a standalone plaintext file,
which makes accessing or updating it trivial.
[mir-opt] Disable the `ConsideredEqual` logic in SimplifyBranchSame opt
The logic is currently broken and we need to disable it to fix a beta
regression (see #76803)
