053383dbef new rules for merging expected/supplied types in closure signatures 
Also, fix numbering in mir-opt tests. We are now anonymizing more
consistently, I think, and hence some of the `TyAnon` indices shifted.

a7d98c7837 Auto merge of #45630 - joshleeb:iss35241, r=estebank 
Improve display of error E0308

Ref. Forgetting to call a variant constructor causes a confusing error message #35241.

This PR modifies [`note_type_err`](b7041bfab3/src/librustc/infer/error_reporting/mod.rs (L669-L674)) to display a `help` message when a `TyFnPtr` or `TyFnDef` are found and the return type, of the function or function pointer, is the same as the type that is expected.

The output of compiling

```rust
struct Foo(u32);

fn test() -> Foo { Foo }

fn main() {}
```

is now

```bash
$ rustc src/test/ui/issue-35241.rs
error[E0308]: mismatched types
  --> src/test/ui/issue-35241.rs:13:20

   |              |
   |              expected `Foo` because of return type

   = help: did you mean `Foo { /* fields */ }`?
   = note: expected type `Foo`
              found type `fn(u32) -> Foo {Foo::{{constructor}}}`

error: aborting due to previous error

2379faa933 Auto merge of #45468 - Xanewok:crate-source, r=nrc 
Emit crate disambiguators in save-analysis data

Needed for https://github.com/nrc/rls-analysis/issues/93.
Blocked by https://github.com/nrc/rls-data/pull/11. (For now, this pulls my branch [rls-data/crate-source](https://github.com/Xanewok/rls-data/tree/crate-source))

This will allow to disambiguate different crates types/versions when indexing resulting save-analysis data (most importantly allow to support bin+lib and different crate versions).

d5b69d4670 Auto merge of #45306 - whitequark:ref_slice, r=alexcrichton 
Bring back slice::ref_slice as slice::from_ref.

These functions were deprecated and removed in 1.5, but such simple
functionality shouldn't require using unsafe code, and it isn't
cluttering libstd too much.

The original removal was quite contentious (see #27774), since then
we've had precedent for including such nuggets of functionality (see rust-lang/rfcs#1789),
and @nikomatsakis has provided a lot of use cases in https://github.com/rust-lang/rfcs/pull/1789#issuecomment-314640034.
Hence this PR.

I'm not too sure what to do with stability, feel free to correct me.
It seems pointless to go through stabilization for these functions though.
