Update windows ffi bindings
Bump `windows-bindgen` to version 0.51.1. This brings with it some changes to the generated FFI bindings, but little that affects the code.
One change that does have more of an impact is `SOCKET` being `usize` instead of either `u64` or `u32` (as is used in std's public `SOCKET` type). However, it's now easy enough to abstract over that difference.
Finally I added a few new bindings that are likely to be used in pending PRs, mostly to make sure they're ok with the new metadata.

Add initial libstd support for Xous
This patchset adds some minimal support to the tier-3 target `riscv32imac-unknown-xous-elf`. The following features are supported:
* alloc
* thread creation and joining
* thread sleeping
* thread_local
* panic_abort
* mutex
* condvar
* stdout
Additionally, internal support for the various Xous primitives surrounding IPC have been added as part of the Xous FFI. These may be exposed as part of `std::os::xous::ffi` in the future, however for now they are not public.
This represents the minimum viable product. A future patchset will add support for networking and filesystem support.
Avoid blessing cargo deps's source code in ui tests
Before this PR, the source code of dependencies was included in UI test error messages whenever possible. Unfortunately, "whenever possible" means in some cases the source code wouldn't be injected, resulting in a test failure.
One such case is when `$CARGO_HOME` is remapped to something that is not present on disk [^1]. As the remapped path doesn't exist on disk, the source code wouldn't be showed in `tests/ui/issues/issue-21763.rs`:
```diff
= note: required for `hashbrown::raw::RawTable<(Rc<()>, Rc<()>)>` to implement `Send`
note: required because it appears within the type `HashMap<Rc<()>, Rc<()>, RandomState>`
--> $HASHBROWN_SRC_LOCATION
- |
-LL | pub struct HashMap<K, V, S = DefaultHashBuilder, A: Allocator + Clone = Global> {
- | ^^^^^^^
note: required because it appears within the type `HashMap<Rc<()>, Rc<()>>`
--> $SRC_DIR/std/src/collections/hash/map.rs:LL:COL
note: required by a bound in `foo`
```
This PR fixes the problem by always hiding dependencies source code in the error messages generated during UI tests. This is implemented with a new internal flag, `-Z ignore-directory-in-diagnostics-source-blocks=$path`, which compiletest passes during UI tests. Once this is merged, remapping the Cargo home will be supported.
This PR is best reviewed commit-by-commit.
[^1]: After being puzzled for a bit, I discovered why this never impacted `rust-lang/rust`: we don't remap `$CARGO_HOME` 😅. Instead, we set `$CARGO_HOME` to `/cargo` in CI, which sort-of-but-not-really achieves the same effect.
Refactor `opt-dist` to simplify local building
This PR refactors the `opt-dist` tool to make it easier to invoke it locally, outside of CI, and thus simplify building PGO/BOLT optimized `rustc` builds e.g. for distro maintainers. It should also make it easier to run the PGO/BOLT workflow locally e.g. to profile performance or debug issues (looking at you, https://github.com/rust-lang/rust/pull/115554).
Replace `rustc_data_structures` dependency with `rustc_index` in `rustc_parse_format`
`rustc_data_structures` is only used for the `static_assert_size` macro, yet that is defined in `rustc_index` and merely re-exported. `rustc_index` is a lot more lightweight than `rustc_data_structures` which would make this a lot more reusable for rust-analyzer.

The Xous operating system has no libc, and relies on `compiler_builtins`
to supply basic functions such as `memcpy`. Bump the version to 0.1.101
to pull in a version of this crate with the flag enabled for Xous.

Make `unconditional_recursion` warning detect recursive drops
Closes#55388
Also closes#50049 unless we want to keep it for the second example which this PR does not solve, but I think it is better to track that work in #57965.
r? `@oli-obk` since you are the mentor for #55388
Unresolved questions:
- [x] There are two false positives that must be fixed before merging (see diff). I suspect the best way to solve them is to perform analysis after drop elaboration instead of before, as now, but I have not explored that any further yet. Could that be an option? **Answer:** Yes, that solved the problem.

Lots of tiny incremental simplifications of `EmitterWriter` internals
ignore the first commit, it's https://github.com/rust-lang/rust/pull/114088 squashed and rebased, but it's needed to use to use `derive_setters`, as they need a newer `syn` version.
Then this PR starts out with removing many arguments that are almost always defaulted to `None` or `false` and replace them with builder methods that can set these fields in the few cases that want to set them.
After that it's one commit after the other that removes or merges things until everything becomes some very simple trait objects
Update lexer emoji diagnostics to Unicode 15.0
This replaces the `unic-emoji-char` dep tree (which hasn't been updated for a while) with `unicode-properties` crate which contains Unicode 15.0 data.
Improves diagnostics for added emoji characters in recent years. (See tests).
