Add `special_module_name` lint
Declaring `lib` as a module is one of the most common beginner mistakes when trying to setup a binary and library target in the same crate. `special_module_name` lints against it, as well as `mod main;`
```
warning: found module declaration for main.rs
--> $DIR/special_module_name.rs:4:1
|
LL | mod main;
| ^^^^^^^^^
|
= note: a binary crate cannot be used as library
warning: found module declaration for lib.rs
--> $DIR/special_module_name.rs:1:1
|
LL | mod lib;
| ^^^^^^^^
|
= note: `#[warn(special_module_name)]` on by default
= note: lib.rs is the root of this crate's library target
= help: to refer to it from other targets, use the library's name as the path
```
Note that the help message is not the best in that it doesn't provide an example of an import path (`the_actual_crate_name::`), and doesn't check whether the current file is part of a library/binary target to provide more specific error messages. I'm not sure where this lint would have to be run to access that information.

ci: Upgrade non-dist Linux testers from ubuntu:16.04 to 22.04

Auto merge of #100869 - nnethercote:replace-ThinVec, r=spastorino
Replace `rustc_data_structures::thin_vec::ThinVec` with `thin_vec::ThinVec`
`rustc_data_structures::thin_vec::ThinVec` looks like this:
```
pub struct ThinVec<T>(Option<Box<Vec<T>>>);
```
It's just a zero word if the vector is empty, but requires two
allocations if it is non-empty. So it's only usable in cases where the
vector is empty most of the time.
This commit removes it in favour of `thin_vec::ThinVec`, which is also
word-sized, but stores the length and capacity in the same allocation as
the elements. It's good in a wider variety of situation, e.g. in enum
variants where the vector is usually/always non-empty.
The commit also:
- Sorts some `Cargo.toml` dependency lists, to make additions easier.
- Sorts some `use` item lists, to make additions easier.
- Changes `clean_trait_ref_with_bindings` to take a
`ThinVec<TypeBinding>` rather than a `&[TypeBinding]`, because this
avoid some unnecessary allocations.

proc_macro/bridge: send diagnostics over the bridge as a struct
This removes some RPC when creating and emitting diagnostics, and
simplifies the bridge slightly.
After this change, there are no remaining methods which take advantage
of the support for `&mut` references to objects in the store as
arguments, meaning that support for them could technically be removed if
we wanted. The only remaining uses of immutable references into the
store are `TokenStream` and `SourceFile`.

Fix UB from misalignment and provenance widening in `std::sys::windows`
This fixes two types of UB:
1. Reading past the end of a reference in types like `&c::REPARSE_DATA_BUFFER` (see https://github.com/rust-lang/unsafe-code-guidelines/issues/256). This is fixed by using `addr_of!`. I think there are probably a couple more cases where we do this for other structures, and will look into it in a bit.
2. Failing to ensure that a `[u8; N]` on the stack is sufficiently aligned to convert to a `REPARSE_DATA_BUFFER`. ~~This was done by introducing a new `AlignedAs` struct that allows aligning one type to the alignment of another type. I expect there are other places where we have this issue too, or I wouldn't introduce this type, but will get to them after this lands.~~
~~Worth noting, it *is* implemented in a way that can cause problems depending on how we fix #81996, but this would be caught by the test I added (and presumably if we decide to fix that in a way that would break this code, we'd also introduce a `#[repr(simple)]` or `#[repr(linear)]` as a replacement for this usage of `#[repr(C)]`).~~
Edit: None of that is still in the code, I just went with a `Align8` since that's all we'll need for almost everything we want to call.
These are more or less "potential UB" since it's likely at the moment everything works fine, although the alignment not causing issues might just be down to luck (and x86 being forgiving).
~~NB: I've only ensured this check builds, but will run tests soon.~~ All tests pass, including stage2 compiler tests.

Use getentropy when possible on all Apple platforms
As the current code comments say, `SecRandomCopyBytes` is very heavyweight (regardless of purpose) compared to just asking the kernel directly for bytes from its own CSPRNG. We were not previously making an attempt to use the more efficient `getentropy` call on other Apple targets, instead solely using it on macOS. As the function is available on newer versions of Apple's different OSes, this changes the random filling to always attempt it first everywhere, only falling back to the less ideal alternatives after. This also cleans up the multiple Apple `imp` blocks into one.
It also should give a perf improvement, even if its likely unnoticeably small.
Refed XCode header for `getentropy` in the SDK:
```h

Reinstate preloading of some dll imports
I've now come around to the conclusion that there is a justification for pre-loading the synchronization functions `WaitOnAddress` and `WakeByAddressSingle`. I've found this to have a particularly impact in testing frameworks that may have short lived processes which immediately spawn lots of threads.
Also, because pre-main initializers imply a single-threaded environment, we can switch back to using relaxed atomics which might be a minor perf improvement on some platforms (though I doubt it's particularly notable).
r? ``@Mark-Simulacrum`` and sorry for the churn here.
For convenience I'll summarise previous issues with preloading and the solutions that are included in this PR (if any):
**Issue:** User pre-main initializers may be run before std's
**Solution:** The std now uses initializers that are guaranteed to run earlier than the old initializers. A note is also added that users should not copy std's behaviour if they want to ensure they run their initializers after std.
**Issue:** Miri does not understand pre-main initializers.
**Solution:** For miri only, run the function loading lazily instead.
**Issue:** We should ideally use `LoadLibrary` to get "api-ms-win-core-synch-l1-2-0". Only "ntdll" and "kernel32" are guaranteed to always be loaded.
**Solution:** None. We can't use `LoadLibrary` pre-main. However, in the past `GetModuleHandle` has always worked in practice so this should hopefully not be a problem.
If/when Windows 7 support is dropped, we can finally remove all this for good and just use normal imports.

Auto merge of #9373 - lukaslueg:result_large_err, r=Alexendoo
Initial implementation `result_large_err`
This is a shot at #6560, #4652, and #3884. The lint checks for `Result` being returned from functions/methods where the `Err` variant is larger than a configurable threshold (the default of which is 128 bytes). There has been some discussion around this, which I'll try to quickly summarize:
* A large `Err`-variant may force an equally large `Result` if `Err` is actually bigger than `Ok`.
* There is a cost involved in large `Result`, as LLVM may choose to `memcpy` them around above a certain size.
* We usually expect the `Err` variant to be seldomly used, but pay the cost every time.
* `Result` returned from library code has a high chance of bubbling up the call stack, getting stuffed into `MyLibError { IoError(std::io::Error), ParseError(parselib::Error), ...}`, exacerbating the problem.
This PR deliberately does not take into account comparing the `Ok` to the `Err` variant (e.g. a ratio, or one being larger than the other). Rather we choose an absolute threshold for `Err`'s size, above which we warn. The reason for this is that `Err`s probably get `map_err`'ed further up the call stack, and we can't draw conclusions from the ratio at the point where the `Result` is returned. A relative threshold would also be less predictable, while not accounting for the cost of LLVM being forced to generate less efficient code if the `Err`-variant is _large_ in absolute terms.
We lint private functions as well as public functions, as the perf-cost applies to in-crate code as well.
In order to account for type-parameters, I conjured up `fn approx_ty_size`. The function relies on `LateContext::layout_of` to compute the actual size, and in case of failure (e.g. due to generics) tries to come up with an "at least size". In the latter case, the size of obviously wrong, but the inspected size certainly can't be smaller than that. Please give the approach a heavy dose of review, as I'm not actually familiar with the type-system at all (read: I have no idea what I'm doing).
The approach does, however flimsy it is, allow us to successfully lint situations like
// We know `UnionError<T>` will be at least 512 bytes, no matter what `T` is
pub fn param_large_union<T: Copy>() -> Result<(), UnionError<T>> {
Ok(())
}
```
I've given some refactoring to `functions/result_unit_err.rs` to re-use some bits. This is also the groundwork for #6409
The default threshold is 128 because of https://github.com/rust-lang/rust-clippy/issues/4652#issue-505670554
`lintcheck` does not trigger this lint for a threshold of 128. It does warn for 64, though.
The suggestion currently is the following, which is just a placeholder for discussion to be had. I did have the computed size in a `span_label`. However, that might cause both ui-tests here and lints elsewhere to become flaky wrt to their output (as the size is platform dependent).
```
error: the `Err`-variant returned via this `Result` is very large

LL | pub fn param_large_error<R>() -> Result<(), (u128, R, FullyDefinedLargeError)> {

21:00:56 Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the links ='libgit2-sys' value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.

```
This is related to the version bump of `libgit2-sys` in #11004, but the root cause is the RLS is sunset (#100863). When the bootstrapper manages the git submodules, the wrong repo commit is checked out. This PR removes rls from the list of rust submodules.
