Rollup merge of #51753 - gruberb:document-from-conversions-libstdpath, r=QuietMisdreavus
Document `From` implementations
This PR is solves part of https://github.com/rust-lang/rust/issues/51430. It's my first PR, so I might need some guidance from @skade (as already mentioned in the issue).
The purpose of the PR is to document the `impl From` inside `path.rs` and answering the questions:
- What does it convert?
- Does it allocate memory?
- How expensive are the allocations?
I gave it a first shot, though an experienced rust developer might want to look over it.

Auto merge of #55871 - ljedrz:llvm_back_allocations, r=nagisa
codegen_llvm_back: improve allocations
This commit was split out from https://github.com/rust-lang/rust/pull/54864. Last time it was causing an LLVM OOM, which was most probably caused by not collecting the globals.
- preallocate vectors of known length
- `extend` instead of `append` where the argument is consumable
- turn 2 `push` loops into `extend`s
- create a vector from a function producing one instead of using `extend_from_slice` on it
- consume `modules` when no longer needed
- ~~return an `impl Iterator` from `generate_lto_work`~~
- ~~don't `collect` `globals`, as they are iterated over and consumed right afterwards~~
While I'm hoping it won't cause an OOM anymore, I would still consider this a "high-risk" PR and not roll it up.

make the C part of compiler-builtins opt-out
I'd like to be able to use Xargo to build a libstd without having a full C toolchain for the target. This is a start (but the fact that libstd is a dylib is still a problem).
However, compiler_builtin already has somewhat similar logic to not require a C compiler for wasm:
(WTF GitHub, why doesn't this show an embedded code preview??)
I wonder if there is a way to not have two separate mechanisms? Like, move the above wasm logic to some place that controls the libstd feature, or so? Or is it okay to have these two mechanisms co-exist?

So there's an error, but not either of the expected kinds. Adding a
format to show the kind revealed `ErrorKind::Interrupted` (`EINTR`).
For the cases that were using `read`, we can just use `read_exact` to
keep trying after interruption. For those using `recv_from`, we have to
manually loop until we get a non-interrupted result.

Enable -mergefunc-use-aliases
If the Rust LLVM fork is used, enable the -mergefunc-use-aliases
flag, which will create aliases for merged functions, rather than
inserting a call from one to the other.
A number of codegen tests needed to be adjusted, because functions
that previously fell below the thunk limit are now being merged.
Merging is prevented in various ways now.
I expect that this is going to break something, somewhere, because
it isn't able to deal with aliases properly, but we won't find out
until we try :)

Consider references and unions potentially inhabited during privacy-respecting inhabitedness checks
It isn't settled exactly how references to uninhabited types and unions of uninhabited types should act, but we should be more conservative here, as it's likely it will be permitted to soundly have values of such types.
This will also be more important in light of the changes at https://github.com/rust-lang/rust/pull/54125.

Run name-anon-globals after all other passes
name-anon-globals should always be run at the very end of the pass
pipeline, as optimization passes (in particular mergefunc) may
introduce new anonymous globals.
I believe we did not run into this earlier because it requires the
rather specific combination of a) mergefunc merging two weak functions
b) compilation not using thinlto.

experiment: Support aliasing local crate root in extern prelude
This PR provides some minimally invasive solution for the 2018 edition migration issue described in https://github.com/rust-lang/rust/issues/54647 and affecting proc macro crates.
`extern crate NAME as RENAME;` now accepts `NAME`=`self` and interprets it as referring to the local crate.
As with other `extern crate` items, `RENAME` in this case gets into extern prelude in accordance with https://github.com/rust-lang/rust/pull/54658, thus resolving https://github.com/rust-lang/rust/issues/54647.
```rust
extern crate self as serde; // Adds local crate to extern prelude as `serde`
```
This solution doesn't introduce any new syntax and has minimal maintenance cost, so it can be easily deprecated if something better is found in the future.
