Rollup merge of #95194 - kckeiks:update-algo-in-find-use-placement, r=pnkfelix
remove find_use_placement

A more robust solution to finding where to place use suggestions was added in #94584.
The algorithm uses the AST to find the span for the suggestion so we pass this span
down to the HIR during lowering and use it instead of calling `find_use_placement`

Fixes #94941

Check var scope if it exist

Fixes #92893.

Added helper function to check the scope of a variable, if it doesn't have a scope call delay_span_bug, which avoids us trying to get a block/scope that doesn't exist.

Had to increase `ROOT_ENTRY_LIMIT` was getting tidy error

Rollup merge of #94461 - jhpratt:2024-edition, r=pnkfelix
Create (unstable) 2024 edition

[On Zulip](https://rust-lang.zulipchat.com/#narrow/stream/213817-t-lang/topic/Deprecating.20macro.20scoping.20shenanigans/near/272860652), there was a small aside regarding creating the 2024 edition now as opposed to later. There was a reasonable amount of support and no stated opposition.

This change creates the 2024 edition in the compiler and creates a prelude for the 2024 edition. There is no current difference between the 2021 and 2024 editions. Cargo and other tools will need to be updated separately, as it's not in the same repository. This change permits the vast majority of work towards the next edition to proceed _now_ instead of waiting until 2024.

For sanity purposes, I've merged the "hello" UI tests into a single file with multiple revisions. Otherwise we'd end up with a file per edition, despite them being essentially identical.

Rollup merge of #94457 - jhpratt:stabilize-derive_default_enum, r=davidtwco
Stabilize `derive_default_enum`

This stabilizes `#![feature(derive_default_enum)]`, as proposed in [RFC 3107](https://github.com/rust-lang/rfcs/pull/3107) and tracked in #87517. In short, it permits you to `#[derive(Default)]` on `enum`s, indicating what the default should be by placing a `#[default]` attribute on the desired variant (which must be a unit variant in the interest of forward compatibility).

1be1157d75 Remove --extern-location and all associated code
`--extern-location` was an experiment to investigate the best way to
generate useful diagnostics for unused dependency warnings by enabling a
build system to identify the corresponding build config.

While I did successfully use this, I've since been convinced the
alternative `--json unused-externs` mechanism is the way to go, and
there's no point in having two mechanisms with basically the same
functionality.

This effectively reverts https://github.com/rust-lang/rust/pull/72603

library: Move `CStr` to libcore, and `CString` to liballoc

Closes https://github.com/rust-lang/rust/issues/46736

Interesting points:
- Stability:
    - To make `CStr(ing)` from libcore/liballoc unusable without enabling features I had to make these structures unstable, and reexport them from libstd using stable type aliases instead of `pub use` reexports. (Because stability of `use` items is not checked.)
- Relying on target ABI in libcore is ok:
    - https://github.com/rust-lang/rust/pull/94079#issuecomment-1044263371
- `trait CStrExt` (UPDATE: used only in `cfg(bootstrap)` mode, otherwise lang items are used instead)
    - https://github.com/rust-lang/rust/pull/94079#issuecomment-1047863450
- `strlen`
    - https://github.com/rust-lang/rust/pull/94079#issuecomment-1047863450

Otherwise it's just a code move + some minor hackery usual for liballoc in `cfg(test)` mode.

93ae6f80e3 Make some usize-typed masks definition agnostic to the size of usize
Some masks where defined as
```rust
const NONASCII_MASK: usize = 0x80808080_80808080u64 as usize;
```
where it was assumed that `usize` is never wider than 64, which is currently true.

To make those constants valid in a hypothetical 128-bit target, these constants have been redefined in an `usize`-width-agnostic way
```rust
const NONASCII_MASK: usize = usize::from_ne_bytes([0x80; size_of::<usize>()]);
```

There are already some cases where Rust anticipates the possibility of supporting 128-bit targets, such as not implementing `From<usize>` for `u64`.

dcc3554c62 Respect ranlib specified for target during LLVM build
The ranlib specified for the target was never actually transferred
into the builder configuration. In the dist-x86_64-linux build we
ended up using ranlib instead of llvm-ranlib.

Windows: Use a pipe relay for chaining pipes

Fixes #95759

This fixes the issue by chaining pipes synchronously and manually pumping messages between them. It's not ideal but it has the advantage of not costing anything if pipes are not chained ("don't pay for what you don't use") and it also avoids breaking existing code that rely on our end of the pipe being asynchronous (which includes rustc's own testing framework).

Libraries can avoid needing this by using their own pipes to chain commands.

clarify doc(cfg) wording
The current "This is supported" wording implies that it's possible to
still use the item on other configurations, but in an unsupported way.
Changing this to "Available" removes this ambiguity.

dd0ad7375e Don't build the library and standard library before documenting them
Rustdoc doesn't require the build artifacts to generate the docs, and
especially in the case of rustc, it greatly increases the time needed to
run the build.

- Statically ensure that only the top_stage of a tool is documented

If another part of rustbuild tried to document a different stage, it
would run into errors because `check::Rustc` unconditionally uses the
top stage.

- Try building rustc instead of checking to avoid duplicate artifacts

Tries to workaround the following error:
```

when checking pointee metadata, canonicalize the `Sized` check

Use `infcx.predicate_must_hold_modulo_regions` with a `Sized` obligation instead of just calling `ty.is_sized`, because the latter does not canonicalize region and type vars (and in the test case I added in this PR, there's a region var in the `ParamEnv`).
