Validation is neither necessary nor desirable.
The validation is already omitted at mir-opt-level >= 3, so there there
are not changes in MIR test output (the propagation of invalid constants
is covered by an existing test in tests/mir-opt/const_prop/invalid_constant.rs).
Restructure and rename std thread_local internals to make it less of a maze
Every time I try to work on std's thread local internals, it feels like I'm trying to navigate a confusing maze made of macros, deeply nested modules, and types with multiple names/aliases. Time to clean it up a bit.
This PR:
- Exports `Key` with its own name (`Key`), instead of `__LocalKeyInner`
- Uses `pub macro` to put `__thread_local_inner` into a (unstable, hidden) module, removing `#[macro_export]`, removing it from the crate root.
- Removes the `__` from `__thread_local_inner`.
- Removes a few unnecessary `allow_internal_unstable` features from the macros
- Removes the `libstd_thread_internals` feature. (Merged with `thread_local_internals`.)
- And removes it from the unstable book
- Gets rid of the deeply nested modules for the `Key` definitions (`mod fast` / `mod os` / `mod statik`).
- Turns a `#[cfg]` mess into a single `cfg_if`, now that there's no `#[macro_export]` anymore that breaks with `cfg_if`.
- Simplifies the `cfg_if` conditions to not repeat the conditions.
- Removes useless `normalize-stderr-test`, which were left over from when the `Key` types had different names on different platforms.
- Removes a seemingly unnecessary `realstd` re-export on `cfg(test)`.
This PR changes nothing about the thread local implementation. That's for a later PR. (Which should hopefully be easier once all this stuff is a bit cleaned up.)

Add new rustdoc book chapter to describe in-doc settings
Fixes#55165.
I continue going through old rustdoc issues. This one made a lot of sense so decided to add the missing chapter.

Spelling library
Split per https://github.com/rust-lang/rust/pull/110392
I can squash once people are happy w/ the changes. It's really uncommon for large sets of changes to be perfectly acceptable w/o at least some changes.
I probably won't have time to respond until tomorrow or the next day
Change tidy error message for TODOs
Blocked on #109440 (first few commits are from where)
IMO "deprecated" doesn't really explain anything, I've tried to highlight the actual reason we error on TODOs. The message is not at all perfect, maybe someone has ideas how to phrase it better?
Add lint to deny diagnostics composed of static strings
r? ghost
I'm hoping to have a lint that semi-automatically converts simple diagnostics such as `struct_span_err(span, "msg").help("msg").span_note(span2, "msg").emit()` to typed session diagnostics. It's quite hacky and not entirely working because of problems with `x fix` but should hopefully help reduce some of the work.
I'm going to start trying to apply what I can from this, but opening this as a draft in case anyone wants to develop on it.

coverage: Don't underflow column number
I noticed this when running coverage on a debug build of rustc. There
may be other places that do this but I'm just fixing the one I hit.

Add regression tests for const-generic inherent associated types
Fixes#109759.
The tests are no longer failing since #96840 which was merged recently (#109410 is no longer necessary for them).

Use the standard macOS CI runner
This moves back to the standard macOS CI runner instead of the large runners. The infra team is discussing whether the large runners are worth the cost at our heavy usage and whether those credits are better spent elsewhere. This will slow down CI build times unfortunately, but while we figure out our CI spending budget, that's a price we'll unfortunately have to pay.

Fix `std` compilation error for wasi+atomics
Fix https://github.com/rust-lang/rust/issues/109727
It seems that the `unsupported/once.rs` module isn't meant to exist at the same time as the `futex` module, as they have conflicting definitions.
I've solved this by defining the `once` module only if `not(target_feature = "atomics")`.
The `wasm32-unknown-unknown` target [similarly only defines the `once` module if `not(target_feature = "atomics")`](01c4f31927/library/std/src/sys/wasm/mod.rs (L69-L70)).
As show in [this block of code](01c4f31927/library/std/src/sys_common/once/mod.rs (L10-L34)), the `sys::once` module doesn't need to exist if `all(target_arch = "wasm32", target_feature = "atomics")`.
