Record `LocalDefId` in HIR nodes instead of a side table
This is part of an attempt to remove the `HirId -> LocalDefId` table from HIR.
This attempt is a prerequisite to creation of `LocalDefId` after HIR lowering (https://github.com/rust-lang/rust/pull/96840), by controlling how `def_id` information is accessed.
This first part adds the information to HIR nodes themselves instead of a table.
The second part is https://github.com/rust-lang/rust/pull/103902
The third part will be to make `hir::Visitor::visit_fn` take a `LocalDefId` as last parameter.
The fourth part will be to completely remove the side table.
Use `token::Lit` in `ast::ExprKind::Lit`.
Instead of `ast::Lit`.
Literal lowering now happens at two different times. Expression literals are lowered when HIR is crated. Attribute literals are lowered during parsing.

rustdoc: remove no-op CSS `#crate-search-div { display: inline-block }`
`#crate-search-div` is nested directly below `.search-results-title`, which has `display: inline-flex`. This makes the crate-search-div a [flex item], which makes its display property irrelevant, because flex items have their display [blockified] in any case.

rustdoc: remove pointless CSS `.rightside { padding-right: 2px }`
This CSS was added in 34bd2b845b, as `.since { padding-right: 2px }`, to prevent it from uncomfortably touching the srclink, which were separate floated elements. It was carried forward with 962c0a4ee5 to the new `.rightside`, but its role was replaced with adding " • " between them. All it does now is pushes the element 2px away from the page's right margin.
Removing this rule changes the page layout, but you have to look for it to notice it.
rustdoc: remove unused JS IIFE from main.js
This [IIFE] made sense when it was added in f0683f98fa and there was a local variable scoped to it, but now it only sets two globals, so it does nothing.

Only do parser recovery on retried macro matching
Eager parser recovery can break macros, so we don't do it at first. But when we already know that the macro failed, we can retry it with recovery enabled to still emit useful diagnostics.
Helps with #103534
cleanup and dedupe CTFE and Miri error reporting
It looks like most of the time, this error raised from const_prop_lint is just redundant -- it duplicates the error reported when evaluating the const-eval query. This lets us make `ConstEvalErr` private to the const_eval module which I think is a good step.
The Miri change mostly replaces a `match` by `if let`, and dedupes the "this error is impossible in Miri" checks.

Issue error when -C link-self-contained option is used on unsupported platforms
The documentation was also updated to reflect this.
I'm assuming the supported platforms are the same as initially written in [RELEASES.md](https://github.com/rust-lang/rust/blob/master/RELEASES.md#compiler-17).
Fixes#103576
rustdoc: remove no-op CSS `.main-header { justify-content }`
This rule was added in 152e888905 to push the out-of-band content to the right while allowing it to line wrap when it got too big. The idea was that the justification rule would fill the space between the `<h1>` element and the `<div class="out-of-band">` element.
A later commit, 3cb03cb342, flattened the in-band element into the `<h1>`, copying the `flex-grow` rule. This means the `<h1>` element now grows to fill the space, so there's no need to justify-content any more.
This commit also adds a test case for this.
rustdoc: remove no-op CSS `.popover { font-size: 1rem }`
This rule was added in cc4f804829 because the help popover inherited the font-size from the help button "?" icon.
It doesn't inherit this any more, because it was moved from being nested inside the link to sharing a wrapper DIV with it.
Fix test/ui/issues/issue-30490.rs
Since the empty main is used for `not(unix)`, all the targets that will use this empty main will also need `allow(unused_imports)`.

Respect visibility & stability of inherent associated types
As discussed in #103621, this probably won't be the final location of the code that resolves inherent associated types. Still, I think it's valuable to push correctness fixes for this feature (in regards to visibility and stability).
Let me know if I should write a translatable diagnostic instead and if I should move the tests to `privacy/` and `stability-attribute/` respectively.
Fixes#104243.

Shift no characters when using raw string literals
Fixes#104142
Given the following code:
```rust
fn main() {
println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#);
}
```
The current output is:
```
error: invalid format string: unmatched `}` found
--> src/main.rs:2:59
|
2 | println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#); //~ ERROR invalid format string: unmatched `}` found
| ^ unmatched `}` in format string
|
= note: if you intended to print `}`, you can escape it using `}}`
error: could not compile `debug_playground` due to previous error
```
The output should look like:
```
error: invalid format string: unmatched `}` found
--> src/main.rs:2:45
|
2 | println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#); //~ ERROR invalid format string: unmatched `}` found
| ^ unmatched `}` in format string
|
= note: if you intended to print `}`, you can escape it using `}}`
error: could not compile `debug_playground` due to previous error
```
This pull request fixes the wrong span for `invalid format string` error and also solves the ICE.
In `codegen_assert_terminator` we decide if a BB's successor is a
candidate for merging, which requires that it be the only successor, and
that it only have one predecessor. That result then gets passed down,
and if it reaches `funclet_br` with the appropriate BB characteristics,
then no `br` instruction is issued, a `MergingSucc::True` result is
passed back, and the merging proceeds in `codegen_block`.
The commit also adds `CachedLlbb`, a new type to help keep track of
each BB that has been merged into its predecessor.
Perform simple scalar replacement of aggregates (SROA) MIR opt
This is a re-open of https://github.com/rust-lang/rust/pull/85796
I copied the debuginfo implementation (first commit) from `@eddyb's` own SROA PR.
This pass replaces plain field accesses by simple locals when possible.
To be eligible, the replaced locals:
- must not be enums or unions;
- must not be used whole;
- must not have their address taken.
The storage and deinit statements are duplicated on each created local.

Literal lowering now happens at two different times. Expression literals
are lowered when HIR is crated. Attribute literals are lowered during
parsing.
This commit changes the language very slightly. Some programs that used
to not compile now will compile. This is because some invalid literals
that are removed by `cfg` or attribute macros will no longer trigger
errors. See this comment for more details:

Walk types more carefully in `ProhibitOpaqueTypes` visitor
The visitor didn't account for the case where you could have `<TAIT as Trait>::Assoc` normalize to itself, in the case of a `type TAIT = impl Trait` with an unconstrained associated type. That causes the visitor to loop on the same type over and over.
Fixes#104291
Deduce closure signature from a type alias `impl Trait`'s supertraits
r? `@oli-obk`
Basically pass the TAIT's bounds through the same method that we're using to deduce a signature from infer var closure bounds.
Does this need a new FCP? I see it as a logical extension of #101834, but happy to rfcbot a new one if it does.
Visit attributes of trait impl items during AST validation
Fixes#104140.
This fix might not be backward compatible (in practice) since we now validate more attributes than before.
Should I write more tests?

Show note where the macro failed to match
When feeding the wrong tokens, it used to fail with a very generic error that wasn't very helpful. This change tries to help by noting where specifically the matching went wrong.
```rust
macro_rules! uwu {
(a a a b) => {};
}
uwu! { a a a c }
```
```diff
error: no rules expected the token `c`
--> macros.rs:5:14

1 | macro_rules! uwu {
| ---------------- when calling this macro
...
4 | uwu! { a a a c }
