PassWrapper: adapt for llvm/llvm-project@b01e2a8b56
A boolean turned into an enum. None matches the old behavior of false, so we pass that.

get rid of a whole bunch of unnecessary rustc_const_unstable attributes
In general, when a `const fn` is still unstable, it doesn't need a `#[rustc_const_unstable]` attribute. The only exception is functions that internally use things that can't be used in stable const fn yet.
So this gets rid of a whole bunch of `#[rustc_const_unstable]` in libcore.
Add `--print host-tuple` to print host target tuple
People often parse `-vV` output to get to the host tuple, which is annoying to do. It's easier to just get it directly.
I called it "host-tuple" instead of "host" because it's clearer that it's just the target name. I'm open to different names, but I think this one is fine.
a quick GitHub search for `'^host` reveals many instances of people doing the parsing, for example:
68e0ca57cd/README.md (L369)0e38473b0c/main.sh (L96)8a3553b865/README.md (L625)43f3ec3970/do.sh (L35)
needs a compiler FCP. I could also do an MCP but I think just an FCP here makes the most sense.

Fix#132013.
There are individual commits that can be their own PR. If the review load is too big, happy to split them off.
We don't see a reason to explicitly pass the default here, so just use
the default instead of explicitly passing it and needing an ifdef.

miri: Directly use rustc_abi
I tried to make this a PR to the miri repo for funsies. Ironically, the integration flow meant that it would use a too-old toolchain hash, and I didn't understand the build system there enough to want to manually fiddle with the hashes.

Remove unintended link
Since `#[link_section]` is enclosed in braces, it was being confused with a link during docs compilation.
This caused compilation to fail when running `x dist` since it emitted a warning regarding broken links.
Fix type reference in documents which was being confused with html tags.
Running `x dist` was failing due to it invoking commands with `-D warnings`, which emitted a warning about unclosed html tags.
library: fix some stability annotations
This PR updates some stability attributes to correctly reflect when some items actually got stabilized. Found while testing https://github.com/rust-lang/rust/pull/132481.
### `core::char` / `std::char`
In https://github.com/rust-lang/rust/pull/26192, the `core::char` module got "stabilized" for 1.2.0, but the `core` crate itself was still unstable until 1.6.0.
In https://github.com/rust-lang/rust/pull/49698, the `std::char` module was changed to a re-export of `core::char`, making `std::char` appear as "stable since 1.2.0", even though it was already stable in 1.0.0.
By marking `core::char` as stable since 1.0.0, the docs will show correct versions for both `core::char` (since 1.6.0) and `std::char` (since 1.0.0). This is also consistent with the stabilities of similar re-exported modules like `core::mem`/`std::mem` for example.
### `{core,std}::array` and `{core,std}::array::TryFromSliceError`
In https://github.com/rust-lang/rust/pull/58302, the `core::array::TryFromSliceError` type got stabilized for 1.34.0, together with `TryFrom`. At that point the `core::array` module was still unstable and a `std::array` re-export didn't exist, but `core::array::TryFromSliceError` could still be named due to https://github.com/rust-lang/rust/pull/95956 to existing yet.
Then, `core::array` got stabilized and `std::array` got added, first targeting 1.36.0 in https://github.com/rust-lang/rust/pull/60657, but then getting backported for 1.35.0 in https://github.com/rust-lang/rust/pull/60838.
This means that `core::array` and `std::array` actually got stabilized in 1.35.0 and `core::array::TryFromSliceError` was accessible through the unstable module in 1.34.0 -- mark them as such so that the docs display the correct versions.
rustdoc: skip stability inheritance for some item kinds
For some item kinds it's incorrect to inherit their parent's stability, because they might be accessible without referring to the parent directly -- This PR removes the stability inheritance for these items and reverts their displayed stability to that before https://github.com/rust-lang/rust/pull/130798.
Impl items, both inherent and trait impls, have a stability, but it is ignored when checking for enabled features. However, impl items are automatically unstable if they're nested inside an unstable module -- this caused the children of impl to inherit the instability and lead to https://github.com/rust-lang/rust/issues/132440.
Furthermore, for associated items only the stability of the associated item itself is checked and not that of its parent impl. This is true even for trait impls and we have [relied on this behavior in the standard library in the past](https://doc.rust-lang.org/1.37.0/std/slice/trait.SliceConcatExt.html#tymethod.concat), so these also shouldn't inherit the impl's stability.
I've also removed the stability inheritance for primitives and keywords so that viewing e.g. [the `i32` docs on `core`](https://doc.rust-lang.org/nightly/core/primitive.i32.html) will no longer show "since 1.6.0". Note that we currently don't annotate stability for the keyword docs, but if we start doing so in the future then this is probably more correct.

Add a bunch of mailmap entries
This adds a bunch of missing mailmap entries for many people. These are needed when using rust-lang/team information in rust-lang/thanks (https://github.com/rust-lang/thanks/pull/53), as the emails there may differ.
These are "easy" ones, where there was a mailmap entry already, making it clear which one is the preferred email address.

Move versioned Apple LLVM targets from `rustc_target` to `rustc_codegen_ssa`
Fully specified LLVM targets contain the OS version on macOS/iOS/tvOS/watchOS/visionOS, and this version depends on the deployment target environment variables like `MACOSX_DEPLOYMENT_TARGET`, `IPHONEOS_DEPLOYMENT_TARGET` etc.
We would like to move this to later in the compilation pipeline, both because it feels impure to access environment variables when fetching target information, but mostly because we need access to more information from https://github.com/rust-lang/rust/pull/130883 to do https://github.com/rust-lang/rust/issues/118204. See also https://github.com/rust-lang/rust/pull/129342#issuecomment-2335156119 for some discussion.
The first and second commit does the actual refactor, it should be a non-functional change, the third commit adds diagnostics for invalid deployment targets, which are now possible to do because we have access to the session.
Tested with the same commands as in https://github.com/rust-lang/rust/pull/130435.

Do not suggest `#[derive(Copy)]` when we wanted a `!Copy` type.
Do not say "`Copy` is not implemented for `T` but `Copy` is".
Do not talk about `Trait` having no implementations when `!Trait` was desired.

The secondary span label is new.
When a trait is not implemented for a type, but there *is* an `impl`
for another type or different trait params, we format the output to
use highlighting in the same way that E0308 does for types.
The logic accounts for 3 cases:
- When both the type and trait in the expected predicate and the candidate are different
- When only the types are different
- When only the trait generic params are different
For each case, we use slightly different formatting and wording.
