Remove an extraneous include
SymbolWrapper.cpp doesn't use std::optional or llvm::Optional, so this patch removes the extraneous include. Note that llvm/ADT/Optional.h has been deprecated upstream. This patch ensures that SymbolWrapper.cpp continues to compile even after the upcoming removal of Optional.h.
Add `--no-undefined-version` link flag and fix associated breakage
LLVM upstream sets `--no-undefined-version` by default in lld: https://reviews.llvm.org/D135402.
Due to a bug in how version scripts are generated, this breaks the `dylib` output type for most crates. See https://github.com/rust-lang/rust/issues/105967#issuecomment-1428671533 for details.
This PR adds the flag to gcc flavor linkers in anticipation of this LLVM change rolling in, and patches `rustc` to not attempt to export `__rust_*` allocator symbols when they weren't generated.
Fixes#105967
Stabilize movbe target feature
Almost all "old" x86 target features are stable. As far as I can tell, these are the last two unstable features in the `x86-64-v2` or `x86-64-v3` microarchitecture levels, so I'm not sure if it was an oversight or if they're still unstable for a reason (see #106323 for `f16c`).
Note that this only stabilizes the target features, and not the intrinsics.

Relax ordering rules for `asm!` operands
The `asm!` and `global_asm!` macros require their operands to appear strictly in the following order:
- Template strings
- Positional operands
- Named operands
- Explicit register operands
- `clobber_abi`
- `options`
This is overly strict and can be inconvienent when building complex `asm!` statements with macros. This PR relaxes the ordering requirements as follows:
- Template strings must still come before all other operands.
- Positional operands must still come before named and explicit register operands.
- Named and explicit register operands can be freely mixed.
- `options` and `clobber_abi` can appear in any position after the template strings.

Introduce a no-op `PlaceMention` statement for `let _ =`.
Fixes https://github.com/rust-lang/rust/issues/54003
Fixes https://github.com/rust-lang/rust/issues/80059
Split from https://github.com/rust-lang/rust/pull/101500
This PR introduces a new `PlaceMention` statement dedicated to matches that neither introduce bindings nor ascribe types. Without this, all traces of the match would vanish from MIR, making it impossible to diagnose unsafety or use in #101500.
This allows to mark `let _ = <unsafe union access or dereference>` as requiring an unsafe block.
Nominating for lang team, as this introduces an extra error.
Fix the docs for pointer method with_metadata_of
The name of the argument to `{*const T, *mut T}::with_metadata_of` was changed from `val` to `meta` recently, but the docs weren't updated to match.

Remove `body_def_id` from `Inherited`
We can just use the body id from the obligation cause.
Follow-up to #108945, only my commit is relevant.

Document the resulting values produced when using `From<bool>` on floats
Have the documentation of the implementation of `From<bool>` on `f32` and `f64` indicate the output values (`0.0` for `false` and `1.0` for `true`).
