CloudABI uses LLVM's libunwind for stack unwinding. There was a small
bug that went by unnoticed, namely that it was not built with -fno-rtti.
This caused it to (indirectly) depend on the entire C++ runtime.
Now that that issue has been resolved, it is also perfectly fine to make
use of this library for programming languages other than C++.
* Bump the release version to 1.25
* Bump the bootstrap compiler to the recent beta
* Allow using unstable rustdoc features on beta - this fix has been applied to
the beta branch but needed to go to the master branch as well.
Force appropriate extension when converting from int to ptr #43291Fixes#43291.
Looking for feedback if I've missed something and/or need to add more tests.

Reword reason for move note
On move errors, when encountering an enum variant, be more ambiguous and do not refer to the type on the cause note, to avoid referring to `(maybe as std::prelude::v1::Some).0`, and instead refer to `the value`.
Sidesteps part of the problem with #41962:
```
error[E0382]: use of partially moved value: `maybe`
--> file.rs:5:30
|
5 | if let Some(thing) = maybe {
| ----- ^^^^^ value used here after move
| |
| value moved here
= note: move occurs because the value has type `std::vec::Vec<bool>`, which does not implement the `Copy` trait
error[E0382]: use of moved value: `(maybe as std::prelude::v1::Some).0`
--> file.rs:5:21
|
5 | if let Some(thing) = maybe {
| ^^^^^ value moved here in previous iteration of loop
= note: move occurs because the value has type `std::vec::Vec<bool>`, which does not implement the `Copy` trait
error: aborting due to 2 previous errors
```

NLL fixes
First, introduce pre-statement effects to dataflow to fix#46875. Edge dataflow effects might make that redundant, but I'm not sure of the best way to integrate them with liveness etc., and if this is a hack, this is one of the cleanest hacks I've seen.
And I want a small fix to avoid the torrent of bug reports.
Second, fix linking of projections to fix#46974

First cut at getting some part of the test suite working for CloudABI
I am currently working on creating a Docker container for automated CI for CloudABI. Here are some of the trivial changes that need to land to make tests pass.
Mention SliceConcatExt's stability in its docs
Just saw someone in IRC mention there being no stable way to join string slices! It isn't entirely clear from the rust documentation that `SliceConcatExt` is usable. While this is mentioned in https://doc.rust-lang.org/std/prelude/, the trait has nothing to indicate that it's currently usable if found via a documentation search.
The wording on this could probably be improved, but I'm hoping its better than nothing.
