rustdoc: remove no-op CSS `h3.variant, .sub-variant h4 { border-bottom: none }`
This rule, added in 69df43b041 to override the default `h4` style, has been obsoleted when a65c98fefb changed it so that only the top docblock put `border-bottom` on `h4.`
Reinstate `hir-stats.rs` test for stage 1.
It was disabled in #94075 for stage 1 because that PR changed type layouts such that the results for this test were different for stage 1 and stage 2. But now that #94075 is in beta, the results for this test are now the same for stage 1 and stage 2.

Manually order `DefId` on 64-bit big-endian
`DefId` uses different field orders on 64-bit big-endian vs. others, in
order to optimize its `Hash` implementation. However, that also made it
derive different lexical ordering for `PartialOrd` and `Ord`. That
caused spurious differences wherever `DefId`s are sorted, like the
candidate sources list in `report_method_error`.
Now we manually implement `PartialOrd` and `Ord` on 64-bit big-endian to
match the same lexical ordering as other targets, fixing at least one
test, `src/test/ui/methods/method-ambig-two-traits-cross-crate.rs`.
Added more const_closure functionality
Enables ConstFnMutClosure to use a tuple of mutable references instead of just a mutable reference to a tuple.
Removes the new function, since it would barely be usable with this new code.

Fix integer overflow in `format!("{:.0?}", Duration::MAX)`
Currently `format!("{:.0?}", Duration::MAX)` causes an integer overflow in the `Duration` `Debug` impl ([playground link](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=67675c6895bdb2e37ee727f0ed7622b2)). This is because the carry from the rounding of the fractional_part into the integer_part will cause the integer_part to overflow as it is already `u64::MAX`. This PR uses a larger integer type to avoid that issue, and adds a test for the correct behaviour.
Adjust the s390x data layout for LLVM 16
LLVM [D131158] changed the SystemZ data layout to always set 64-bit
vector alignment, which used to be conditional on the "vector" feature.

rustdoc: remove no-op source sidebar `opacity`
These rules were added in dc2c972334 to work with CSS transitions. They're otherwise redundant, since the `visibility` property already hides everything.
dc2c972334/src/librustdoc/html/static/css/rustdoc.css (L350-L354)
The transition was remove with 237d62588d, but the now-redundant `opacity` property was not.
rustdoc: remove unneeded CSS `.rust-example-rendered { position }`
The Run button isn't inside the `<pre>` any more. It's instead nested below the example wrapper.

Improve errors for incomplete functions in struct definitions
Given the following code:
```rust
fn main() {}
struct Foo {
fn
}
```
[playground](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=29139f870511f6918324be5ddc26c345)
The current output is:
```
Compiling playground v0.0.1 (/playground)

= help: unlike in C++, Java, and C#, functions are declared in `impl` blocks
= help: see https://doc.rust-lang.org/book/ch05-03-method-syntax.html for more information

```
In this case, rustc should suggest escaping `fn` to use it as an identifier.

Split out the error reporting logic into a separate function
I was trying to read the function and got distracted by the huge block of code in the middle of it. Turns out it only reports diagnostics and all paths within it end in an error. The main function is now more readable imo.
tidy: make rustc dependency error less confusing
The current wording leads to very confusing messages:
```
tidy error: Dependencies for main workspace not explicitly permitted:
* unicode-ident 1.0.4 (registry+https://github.com/rust-lang/crates.io-index)
```
Miri is part of that workspace, and there never was a problem adding Miri dependencies. The actual error is that due to a crate bump this now showed up as a rustc dependency, and *those* are restricted.
rustdoc: remove bad CSS font-weight on `.impl`, `.method`, etc
This line was added in c494a06064, because at the time, the headers had these classes on them. Now, the headers are children of the `<section>` with the class on it.
This commit also adds a test case, to make sure the srclink font weight does not regress again.
Don't export `__wasm_init_memory` on WebAssembly.
Since #72889, the Rust wasm target doesn't use --passive-segments, so remove the `--export=__wasm_init_memory`.
As documented in the [tool-conventions Linking convention], `__wasm_init_memory` is not intended to be exported.

Fix span of byte-escaped left format args brace
Fix#102057 (see issue for example).
Previously, the use of escaped left braces (`\x7B`) in format args resulted in an incorrectly offset span. This patch fixes that by considering any escaped characters within the string instead of using a constant offset.
The Run button isn't inside the `<pre>` any more. It's instead nested below
the example wrapper.

Fix perf regression from TypeVisitor changes
Regression occurred in https://github.com/rust-lang/rust/pull/101858#issuecomment-1248732579
Instead of just reverting, we only fixed part of the regression. The main regression was due to actually correctly visiting a type that contains types and consts and should therefor be visited. This is not actually observable (yet?), but we should still do it correctly instead of risking major bugs in the future.
rustdoc: clean up "normalize.css 8" input override CSS
These rules were copied from normalize.css 3, and are mostly redundant.
* `optgroup` isn't used in rustdoc at all
* `textarea` is only used for the "copy" button, so it's not visible
* The remaining buttons and inputs mostly have styles set anyway.
* We should never be setting `color` without also setting the background to something. Otherwise, you get white-on-gray text. That seems to be [the reason] why `normalize.css` changed this.
[the reason]: https://github.com/necolas/normalize.css/pull/502
Don't export `__heap_base` and `__data_end` on wasm32-wasi.
`__heap_base` and `__data_end` are exported for use by wasm-bindgen, which uses the wasm32-unknown-unknown target. On wasm32-wasi, as a step toward implementing the Canonical ABI, and as an aid to building speicalized WASI API polyfill wrappers, don't export `__heap_base` and `__data_end` on wasm32-wasi.
