UnreachableProp: Preserve unreachable branches for multiple targets

Before, UnreachablePropagation removed all unreachable branches. This was a pessimization, as it removed information about reachability that was used later in the optimization pipeline.

For example, this code
```rust
pub enum Two { A, B }
pub fn identity(x: Two) -> Two {
    match x {
        Two::A => Two::A,
        Two::B => Two::B,
    }
}
```

basically has `switchInt() -> [0: 0, 1: 1, otherwise: unreachable]` for the match. This allows it to be transformed into a simple `x`. If we remove the unreachable branch, the transformation becomes illegal.

This was the problem keeping `UnreachablePropagation` from being enabled, so we can enable it now.

Something similar already happened in #77800, but it did not show a perf improvement there. Let's try it again anyways!

Fixes #68105, although that issue has been fixed for a long time (see #77680).

Rollup merge of #100872 - JanBeh:PR_vec_default_alloc_doc, r=fee1-dead
Add guarantee that Vec::default() does not alloc

Currently `Vec::new()` is guaranteed to not allocate until elements are pushed onto the `Vec`, but such a guarantee is missing for `Vec`'s implementation of `Default::default`.

This adds such a guarantee for `Vec::default()` to the API reference.

See also [this discussion on URLO](https://users.rust-lang.org/t/guarantee-that-vec-default-does-not-allocate/79903).

Rollup merge of #100331 - lo48576:try-reserve-preserve-on-failure, r=thomcc
Guarantee `try_reserve` preserves the contents on error

Update doc comments to make the guarantee explicit. However, some
implementations does not have the statement though.

* `HashMap`, `HashSet`: require guarantees on hashbrown side.
* `PathBuf`: simply redirecting to `OsString`.

Fixes #99606.

Rollup merge of #99957 - chotchki:ip-globally-reachable_rebase, r=Mark-Simulacrum
Rework Ipv6Addr::is_global to check for global reachability rather than global scope - rebase

Rebasing of pull request #86634 off of master to try and get the feature "ip" stabilized.

I also found a test failure in the rebase that is_global was considering the benchmark space to be globally reachable.

This is related to my other rebasing pull request #99947

Rollup merge of #99770 - Nilstrieb:mir-pass-unit-test, r=oli-obk
Make some const prop mir-opt tests `unit-test`s

Most of these have no or only tiny diffs beyond line numbers being changed (would it make sense to not have line numbers in mir-opt tests?). Some things changed a bit, but I think it should all be fine, not sure though.

Rollup merge of #98200 - ouz-a:issue-98177, r=oli-obk
Expand potential inner `Or` pattern for THIR

Code assumed there wouldn't be a deeper `Or` pattern inside expanded `PatStack` this fixes it by looking for the `Or` pattern inside expanded `PatStack`.

A more ideal solution would be recursively doing this but I haven't found a good way to do that.

e0dc8d7801 Auto merge of #99908 - Nilstrieb:mir-opt-span, r=oli-obk
Show absolute line numbers if span is outside relative span

In the MIR pretty printing, it can sometimes happen that the span of the statement is outside the span of the body (for example through inlining). In this case, don't display a relative span but an absolute span. This will make the mir-opt-tests a little more prone to diffs again, but the impact should be small.

Fixes #99854

a8a33cf271 Auto merge of #99702 - SparrowLii:transtive_relation, r=oli-obk
get rid of `RefCell` in `TransitiveRelation`

This is one of the jobs in `Pending refactorings` in #48685. The parallel-compiler's work has been suspended for quite some time, but I think I can pick it up gradually. I think this PR should be a start.

Regarding the refactoring of `TransitiveRelation`, `@nikomatsakis`  has proposed [two(three?) schemes](https://github.com/rust-lang/rust/pull/48587#issuecomment-369336651). In order to satisfy both compilation efficiency and robustness, I think adding the `freeze` method may be the best solution, although it requires relatively more code changes.
