Use rustc-stable-hash in the compiler
Following https://github.com/rust-lang/compiler-team/issues/755 and the release of the crate on crates.io, let's now use it in the compiler and remove the old implementation.

compiletest: Better error message for bad `normalize-*` headers
Follow-up to #126777.
Example of the new error message in context:
```text
---- [ui] tests/ui/rfcs/rfc-2632-const-trait-impl/effects/minicore.rs stdout ----
thread '[ui] tests/ui/rfcs/rfc-2632-const-trait-impl/effects/minicore.rs' panicked at src/tools/compiletest/src/header.rs:1001:13:
couldn't parse custom normalization rule: `normalize-stderr-test ".*note: .*\n\n" -> ""`
help: expected syntax is: `normalize-stderr-test: "REGEX" -> "REPLACEMENT"`
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
Require a colon in `//@ normalize-*:` test headers
The previous parser for `//@ normalize-*` headers (before #126370) was so lax that it did not require `:` after the header name. As a result, the test suite contained a mix of with-colon and without-colon normalize headers, both numbering in the hundreds.
This PR updates the without-colon headers to add a colon (matching the style used by other headers), and then updates the parser to make the colon mandatory.
(Because the normalization parser only runs *after* the header system identifies a normalize header, this will detect and issue an error for relevant headers that lack the colon.)
Addresses one of the points of #126372.
feat: do not add new enum if it already exists
## Summary
This PR introduces a check for the existence of another enum within the current scope, and if it exist, we skip `add_enum_def`.
## Why?
Currently, when using the `bool_to_enum` assist more than once, it is possible to add multiple enum definitions. For example, the following snippet,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = true;
println!("Hello, world!");
}
```
will be transformed into,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = Bool::True;
println!("Hello, world!");
}
```
This can be annoying for users to clean up.
Migrate `issue-83112-incr-test-moved-file`, `type-mismatch-same-crate-name` and `issue-109934-lto-debuginfo` `run-make` tests to rmake or ui
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
I have noticed that the new UI test `debuginfo-lto-alloc` is outputting artifacts that aren't getting cleaned up because of its `-C incremental`. That might be the justification needed to keep it as a run-make test?

Fix libc::read shim: make it write to a buffer correct amount of bytes. Add tests for new behavior
libc::read shim had a bug: if underlying real call libc::read(fd, buf, N) returns M, then
libc::read shim writes N bytes to buf instead of M. Remaining N - M bytes are filled with zeros.
This commit fixes this bug and adds tests for new behavior
Add `f16` and `f128` support
Adds `f16` and `f128` support, using the `rustc_apfloat` library (also used by `rustc`) for parsing/arithmetic/displaying since the types aren't stable yet so can't be used by rust-analyzer itself.
Issue: #17451
feat: add inlay hints for generic parameters
fixes#11091
By default, only hints for const generic parameters are shown, and this can be configured through `rust-analyzer.inlayHints.genericParameterHints.enable`.
Probably needs more testing.

`cdylib-fewer-symbols` demands a Windows try-job. (Almost guaranteed to fail, but 7 years is a long time)

This commit fixes this bug and adds tests for new behavior
This commit promotes the `wasm32-wasip2` Rust target to tier 2 as
proposed in rust-lang/compiler-team#760. There are two major changes in
this PR:
1. The `dist-various-2` container, which already produces the other WASI
targets, now has an extra target added for `wasm32-wasip2`.
2. A new `wasm-component-ld` binary is added to all host toolchains when
LLD is enabled. This is the linker used for the `wasm32-wasip2` target.
This new linker is added for all host toolchains to ensure that all host
toolchains can produce the `wasm32-wasip2` target. This is similar to
how `rust-lld` was originally included for all host toolchains to be
able to produce WebAssembly output when the targets were first added.
The new linker is developed [here][wasm-component-ld] and is pulled in
via a crates.io-based dependency to the tree here.

Move trait selection error reporting to its own top-level module
This effectively moves `rustc_trait_selection::traits::error_reporting` to `rustc_trait_selection::error_reporting::traits`. There are only a couple of actual changes to the code, like moving the `pretty_impl_header` fn out of the specialization module for privacy reasons.
This is quite pointless on its own, but having `error_reporting` as a top-level module in `rustc_trait_selection` is very important to make sure we have a meaningful file structure for when we move **type** error reporting (and region error reporting, with which it's incredibly entangled currently) into `rustc_trait_selection`. I've opened a tracking issue here: #127492

Implement support for multiple TLS destructors on macOS
I want to get rid of [this `#[cfg]` block](98dcbae5c9/library/std/src/thread/mod.rs (L195-L211)) in `std`, but it is currently required for miri, as it does not support multiple macOS TLS destructors. This is not true for the platform itself, however, as can be observed in the [implementation](d552c40cd1/dyld/DyldRuntimeState.cpp (L2239)).
