make non_camel_case_types an early lint
This allows us to catch these kinds of style violations much earlier, as evidenced by the large number of tests that had to be updated for this change.
Revert #56944.
This should fix#57111, since #56944 is the only PR involving LLVM.
#57111 is caused by both the rustc and rust-std tarballs providing libLLVM.

Update the stdsimd submodule
This brings in a few updates:
* Update wasm intrinsic naming for atomics
* Update and reimplement most simd128 wasm intrinsics
* Other misc improvements here and there, including a small start to
AVX-512 intrinsics
std: Use backtrace-sys from crates.io
This commit switches the standard library to using the `backtrace-sys`
crate from crates.io instead of duplicating the logic here in the Rust
repositor with the `backtrace-sys`'s crate's logic.
Eventually this will hopefully be a good step towards using the
`backtrace` crate directly from crates.io itself, but we're not quite
there yet! Hopefully this is a small incremental first step we can take.
x.py: fixup 6130fc884b, fix submodule handling
./x.py used to automatically check out the right commit when a submodule was outdated and ./x.py build was run
and submodules handling was enabled in config.toml (submodules = true).
But it threw an error:
[...]
failed to run: git submodule -q sync --progress src/tools/clippy
The commit removes the --progress from git submodule call.
Fixes#57080

docs(rustc): make hello() public
Running the example code [here](https://doc.rust-lang.org/rustc/what-is-rustc.html#basic-usage) throws error:
```
error[E0603]: function `hello` is private
--> src/main.rs:4:10
|
4 | foo::hello();
| ^^^^^
```
Making `hello()` public fixes the problem.
librustc_codegen_llvm: Don't eliminate empty structs in C ABI on linux-sparc64
This is in accordance with the SPARC Compliance Definition 2.4.1,
Page 3P-12. It says that structs of up to 8 bytes (which applies
to empty structs as well) are to be passed in one register.
Enable emission of alignment attrs for pointer params
Instead disable creation of assumptions during inlining using an LLVM opt flag. For non-inlined functions, this gives us alignment information, while not inserting any assumes that kill other optimizations.
The `-Z arg-align-attributes` option which previously controlled this behavior is removed.
Fixes#54982.
r? @nagisa
cc @eddyb who added the current behavior, and @scottmcm, who added the `-Z arg-align-attributes` flag.
Actually run compiletest tests on CI
I was assuming that https://github.com/rust-lang/rust/pull/56792 would
have resulted in compiletest tests being executed on CI. However, I
couldn't find any mentions of the unit test names in any CI logs.
This adds the compiletest test execution to the checktools.sh script.
rustc: Move jemalloc from rustc_driver to rustc
This commit moves jemalloc to just the rustc binary rather than the
rustc_driver shared library, enusring that it's only used for binaries
that opt-in to it like rustc rather than other binaries using
librustc_driver like rustdoc/rls/etc. This will hopefully address #56980
bootstrap: Link LLVM as a dylib with ThinLTO
When building a distributed compiler on Linux where we use ThinLTO to
create the LLVM shared object this commit switches the compiler to
dynamically linking that LLVM artifact instead of statically linking to
LLVM. The primary goal here is to reduce CI compile times, avoiding two+
ThinLTO builds of all of LLVM. By linking dynamically to LLVM we'll
reuse the one ThinLTO step done by LLVM's build itself.
Lots of discussion about this change can be found [here] and down. A
perf run will show whether this is worth it or not!

box: Add documentation for `From` impls
This is a part of #51430. A brief description of the behaviour and examples are added to the documentation.
I am not sure what sort of examples to put for the `From` for `Pin` as my [code](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2015&gist=97c908f44e41c9faeffec5b61d72a03e) doesn't even manage to compile using the nightly build.
Somehow I feel that I missed out something so do let me know if more information is needed in the documentation or any of the examples require change.

Fix alignment for array indexing
We need to reduce the alignment with the used offset. If the offset isn't known, use the element size, as this will yield the minimum possible alignment.
This handles both direct array indexing, and array repeat expressions.
Fixes#56927.
