Distribute rustc sources as part of `rustc-dev`

They can be used to provide IDE features when working on rustc plugins/backends/etc without having to locate a separate Rust checkout.

2cbc570e58 Auto merge of #76884 - Mark-Simulacrum:fix-macos-ci, r=pietroalbini
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.

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.~~

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.

BTreeMap: avoid slices even more

Epilogue to #73971: it seems the compiler is unable to realize that creating a slice and `get_unchecked`-ing one element is a simple fetch. So try to spell it out for the only remaining but often invoked case.

Also, the previous code doesn't seem fair game to me, using `get_unchecked` to reach beyond the end of a slice. Although the local function `slice_insert` also does that.

f583513dc2 Intorduced MiniMap - a tiny small storage optimized map implementation
This makes everything about 1% faster in rustc-perf,
mostly negating performance hit of previous commit.

17d2e3b5d2 Better handling for exponential-sized types in misc places
Mostly to fix ui/issues/issue-37311-type-length-limit/issue-37311.rs.

Most parts of the compiler can handle deeply nested types with a lot
of duplicates just fine, but some parts still attempt to naively
traverse type tree.

Before such problems were caught by type length limit check,
but now these places will have to be changed to handle
duplicated types gracefully.

2f3296192b Only visit types once when walking the type tree
This fixes #72408.

Nested closures were resulting in exponential compilation time.

As a performance optimization this change introduces MiniSet,
which is a simple small storage optimized set.

f3c923a13a Auto merge of #76645 - fusion-engineering-forks:windows-lock, r=kennytm
Small cleanups in Windows Mutex.

 - Move `held` into the boxed part, since the SRW lock implementation does not use this. This makes the Mutex 50% smaller.
 - Use `Cell` instead of `UnsafeCell` for `held`, such that `.replace()` can be used.
 - Add some comments.
 - Avoid creating multiple `&mut`s to the critical section object in `ReentrantMutex`.

move guaranteed{ne,eq} implementation to compile-time machine

Currently, Miri needs a special hack to avoid using the core engine implementation of these intrinsics. That seems silly, so let's move them to the CTFE machine, which is the only machine that wants to use them.

I also added a reference to https://github.com/rust-lang/rust/issues/73722 as a warning to anyone who wants to adjust `guaranteed_eq`.

Improve E0118

- Changes the "base type" terminology to "nominal type" (according to the [reference](https://doc.rust-lang.org/stable/reference/items/implementations.html#inherent-implementations)).
- Suggests removing a reference, if one is present on the type.
- Clarify what is meant by a "nominal type".

closes #69392

This is my first not-entirely-trivial PR, so please let me know if I missed anything or if something could be improved. Though I probably won't be able to fix anything in the upcoming week.
