These are happening since the switch to universes, and will now go through the "placeholder error" path, instead of the current fallback of E308 "mismatched types" errors.
remove deprecated suggestion functions
This PR removes the (now unused) deprecated suggestion functions and removes `_with_applicability` from their replacements' names.
This PR will break clippy, but I'll open a clippy PR once this is merged.
Ignore aarch64 in simd-intrinsic-generic-reduction
This fails on AArch64 see https://github.com/rust-lang/rust/issues/54510
Disabling it for now until it's fixed/implemented in LLVM

Fix some minor warnings
Since apparently RLS works when initialized in the root repository (🎉) I decided to fix some of the issues it caught.
There are a lot of unused attribute warnings left on `rustc_on_unimplemented` and `rustc_layout_scalar_valid_range_start` but I imagine we can't do much about it due to 2-stage compilation?
Suggest removing leading left angle brackets.
Fixes#57819.
This PR adds errors and accompanying suggestions as below:
```
bar::<<<<<T as Foo>::Output>();
^^^ help: remove extra angle brackets

std: Stabilize fixed-width integer atomics
This commit stabilizes the `Atomic{I,U}{8,16,32,64}` APIs in the
`std::sync::atomic` and `core::sync::atomic` modules. Proposed in #56753
and tracked in #32976 this feature has been unstable for quite some time
and is hopefully ready to go over the finish line now!
The API is being stabilized as-is. The API of `AtomicU8` and friends
mirrors that of `AtomicUsize`. A list of changes made here are:
* A portability documentation section has been added to describe the
current state of affairs.
* Emulation of smaller-size atomics with larger-size atomics has been
documented.
* As an added bonus, `ATOMIC_*_INIT` is now scheduled for deprecation
across the board in 1.34.0 now that `const` functions can be invoked
in statics.
Note that the 128-bit atomic types are omitted from this stabilization
explicitly. They have far less platform support than the other atomic
types, and will likely require further discussion about their best
location.
Closes#32976Closes#56753
Implement optimize(size) and optimize(speed) attributes
This PR implements both `optimize(size)` and `optimize(speed)` attributes.
While the functionality itself works fine now, this PR is not yet complete: the code might be messy in places and, most importantly, the compiletest must be improved with functionality to run tests with custom optimization levels. Otherwise the new attribute cannot be tested properly. Oh, and not all of the RFC is implemented – attribute propagation is not implemented for example.
# TODO
* [x] Improve compiletest so that tests can be written;
* [x] Assign a proper error number (E9999 currently, no idea how to allocate a number properly);
* [ ] Perhaps reduce the duplication in LLVM attribute assignment code…
Rebase to the llvm-project monorepo
The new git submodule src/llvm-project is a monorepo replacing src/llvm
and src/tools/{clang,lld,lldb}. This also serves as a rebase for these
projects to the new 8.x branch from trunk.
The src/llvm-emscripten fork is unchanged for now.
