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`.

7bdb5dee7b Auto merge of #76634 - RalfJung:miri-guaranteed-eq-ne, r=oli-obk 
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`.

The use of arith_offset was added in 803e9ae67b770d8500c4ab5862e988d29118356a
before the stable wrapper of the intrinsic was available.

95386b656e Auto merge of #76028 - aticu:improve_e0118, r=estebank,jyn514,GuillaumeGomez 
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.

f4a7149f49 Don't compile regex at every function call. 
Use `SyncOnceCell` to only compile it once.
I believe this still adds some kind of locking mechanism?

Alternative to PR #76776.

To change the graphviz output to use an alternative `fontname` value,
