Clean up unchecked_math, separate out unchecked_shifts
Tracking issue: #85122
Changes:
1. Remove `const_inherent_unchecked_arith` flag and make const-stability flags the same as the method feature flags. Given the number of other unsafe const fns already stabilised, it makes sense to just stabilise these in const context when they're stabilised.
2. Move `unchecked_shl` and `unchecked_shr` into a separate `unchecked_shifts` flag, since the semantics for them are unclear and they'll likely be stabilised separately as a result.
3. Add an `unchecked_neg` method exclusively to signed integers, under the `unchecked_neg` flag. This is because it's a new API and probably needs some time to marinate before it's stabilised, and while it *would* make sense to have a similar version for unsigned integers since `checked_neg` also exists for those there is absolutely no case where that would be a good idea, IMQHO.
The longer-term goal here is to prepare the `unchecked_math` methods for an FCP and stabilisation since they've existed for a while, their semantics are clear, and people seem in favour of stabilising them.

rustdoc: Document lack of object safety on affected traits
Closes #85138
I saw the issue didn't have any recent activity, if there is another MR for it I missed it.
I want the issue to move forward so here is my proposition.
It takes some space just before the "Implementors" section and only if the trait is **not** object
safe since it is the only case where special care must be taken in some cases and this has the
benefit of avoiding generation of HTML in (I hope) the common case.

Accept less invalid Rust in rustdoc
pulled out of https://github.com/rust-lang/rust/pull/117213 where this change was already approved
This only affects rustdoc, and has up to [20% perf regressions in rustdoc](https://github.com/rust-lang/rust/pull/117213#issuecomment-1785776288). These are unavoidable, as we are simply doing more checks now, but it's part of the longer term plan of making rustdoc more resistant to ICEs by only accepting valid Rust code.

Store #[deprecated] attribute's `since` value in parsed form
This PR implements the first followup bullet listed in https://github.com/rust-lang/rust/pull/117148#issue-1960240108.
We centralize error handling to the attribute parsing code in `compiler/rustc_attr/src/builtin.rs`, and thereby remove some awkward error codepaths from later phases of compilation that had to make sense of these #\[deprecated\] attributes, namely `compiler/rustc_passes/src/stability.rs` and `compiler/rustc_middle/src/middle/stability.rs`.

improve and fix `x install`
Fix: Write access check of `prefix` and `sysconfdir` when DESTDIR is present.
Improvement: Instead of repeatedly reading `DESTDIR` within each `fn prepare_dir` usage, read it once and pass it to the `fn prepare_dir`.
Fixes #117203

More `rustc_interface` cleanups
In particular, following up #117268 with more improvement to `--cfg`/`--check-cfg` handling.

rustdoc: elide cross-crate default generic arguments
Elide cross-crate generic arguments if they coincide with their default.
TL;DR: Most notably, no more `Box<…, Global>` in `std`'s docs, just `Box<…>` from now on.
Fixes #80379.
Also helps with #44306. Follow-up to #103885, #107637.

update which targets we test Miri on
I hope this doesn't cost too much time; running only the "pass" tests should be reasonably fast (1-2 minutes on my system).

this also updates target-sensitive dependencies like rustix
and libc.

By storing the unparsed values in `Config` and then parsing them within
`run_compiler`, the parsing functions can use the main symbol interner,
and not create their own short-lived interners.
This change also eliminates the need for one `EarlyErrorHandler` in
rustdoc, because parsing errors can be reported by another, slightly
later `EarlyErrorHandler`.

pass `CODEGEN_BACKENDS` to docker
The backends to build are now defined in the `CODEGEN_BACKENDS` env var. It's correctly set in CI, but wasn't passed to docker, hence cg_clif wasn't actually built in #81746.
r? `@Kobzol:` I locally tried `CODEGEN_BACKENDS="cranelift" DEPLOY=1 src/ci/docker/run.sh dist-x86_64-linux` and this change was enough for `ci/run.sh` to read the env var.
So I'll try as-is and we'll see.

See through aggregates in GVN
This PR is extracted from https://github.com/rust-lang/rust/pull/111344
The first 2 commit are cleanups to avoid repeated work. I propose to stop removing useless assignments as part of this pass, and let a later `SimplifyLocals` do it. This makes tests easier to read (among others).
The next 3 commits add a constant folding mechanism to the GVN pass, presented in https://github.com/rust-lang/rust/pull/116012. ~This pass is designed to only use global allocations, to avoid any risk of accidental modification of the stored state.~
The following commits implement opportunistic simplifications, in particular:
- projections of aggregates: `MyStruct { x: a }.x` gets replaced by `a`, works with enums too;
- projections of arrays: `[a, b][0]` becomes `a`;
- projections of repeat expressions: `[a; N][x]` becomes `a`;
- transform arrays of equal operands into a repeat rvalue.
Fixes https://github.com/rust-lang/miri/issues/3090

rustdoc: Use `ThinVec` in `GenericParamDefKind`
This should hopefully reduce memory usage and improve performance since
these vectors are often empty (and `GenericParamDefKind` is constructed *a lot*).

add bootstrap flag `--skip-stage0-validation`
This change introduces the `--skip-stage0-validation` flag, which permits the use of any desired version of the stage0 compiler without verifying its version.
Additionally, stage0 compiler validation check is reverted(#115103) to its default enabled state.
Helps to #115065

change default output mode of `BootstrapCommand`
`SuppressOnSuccess` on `BootstrapCommand` is a problematic default mode as it affects the logs during the bootstrapping (as shown in the screenshot below). The default behavior should be to print everything unless we explicitly modify the behavior within build steps.
Fixes #117315

Add support for i586-unknown-netbsd as target.
This restricts instructions to those offered by Pentium, to support e.g. AMD Geode.
There is already an entry for this target in the NetBSD platform support page at
src/doc/rustc/src/platform-support/netbsd.md
...so this should forestall its removal.
Additional fixes are needed for some vendored modules, this is the changes in the rust compiler core itself.
