c921abf9c0 Stabilise f32::to_{degrees,radians} to match f64
f64 methods have been stable since rust 1.0, but f32 never got stabilised.

When looking in the documentation I often scan the examples the first thing I do. In these 3 cases it's not obvious which direction the operation happens by adding this comment it makes it more obvious.

Are trait impls still insta-stable? Considering that this design has been around for a long time on `String` and `OsString` it probably doesn't matter much...

The `From` impl is a bit strange to me. It's stolen from `OsString` but I'm not really sure about it... `String` just impls `From<&str>` instead, would that make more sense?

7448f4861a Rollup merge of #30630 - tsion:mir-closure-args, r=nagisa
Previously, all references to closure arguments went to the argument before the one they should (e.g. to `arg1` when it was supposed to go to `arg2`). This was because the MIR builder did not account for the implicit arguments that come before the explicit arguments, and closures have one implicit argument - the struct containing the captures.

This is my test code and a diff of the MIR generated for the closure:

```rust
let a = 2i32;
let _f = |b: i32| -> i32 { a + b }:
```

1aa4abdb3b Rollup merge of #30590 - nagisa:mir-constval-function, r=luqmana
This moves back (essentially reverts #30265) into MIR-specific translation code, but keeps the
funcition split out, since it is expected to eventually become recursive.

Fixes https://github.com/rust-lang/rust/issues/29572

23d24ff667 Rollup merge of #30565 - michaelwoerister:opaque_encoder, r=brson
This PR changes the `emit_opaque` and `read_opaque` methods in the RBML library to use a space-efficient binary encoder that does not emit any tags and uses the LEB128 variable-length integer format for all numbers it emits.

The space savings are nice, albeit a bit underwhelming, especially for dynamic libraries where metadata is already compressed.

| libsyntax     |  7.8 MB   | 8.4 MB |

At least this should make up for the size increase caused recently by also storing MIR in crate metadata.

Can this be a breaking change for anyone?

This hairy conditional doesn't need to be so. It _does_ need to be a
thin pointer, otherwise, it will fail to compile, so let's pull that out

Also, after a discussion with @pnkfelix and @gankro, we don't need these
null checks anymore, as zero-on-drop has been gone for a while now.
