use unsigned_abs instead of `abs` on signed int to silence clippy
Use `unsigned_abs` instead of `abs` on signed int to silence clippy. Alternatively we could allow the lint, but if codegen is not affected, then this seems preferable.

Fast path nitpicks
Miscellaneous commits that I didn't really want to fold into anything else.
Fixes one theoretical bug with the fast path not considering polarity for `T: !Sized` bounds.
MIR inliner maintains unused var_debug_info
Only `full` debuginfo level promises variable-level debug information, but the MIR inline pass needlessly preserved the local variable debug info for the `limited` level too.
Post {beta,stable}-accepted notifications to compiler/bootstrap backport zulip channels on `{beta,stable}-accepted` label application
The first commit slightly reorganizes `triagebot.toml` (no functional changes) with some dividing sections, because I found it hard to find the actual sections.
The second and third commit configures triagebot to post
> PR #`{number}` has been **accepted** for **{beta,stable}** backport.
to compiler/bootstrap backport threads respectively, when https://github.com/rust-lang/rust/labels/beta-accepted and https://github.com/rust-lang/rust/labels/stable-accepted labels are applied.
Best reviewed commit-by-commit.

minicore: use core's `diagnostic::on_unimplemented` messages
Without these attributes, the error message is different. Keeping the diagnostics up-to-date seems related to https://github.com/rust-lang/rust/issues/137531.
The modified test files are reported in https://github.com/rust-lang/rust/issues/143319 as failing for `--target=riscv64gc-unknown-linux-gnu`. Using `minicore` for them makes it easier to troubleshoot this sort of issue.

setup typos check in CI
This allows to check typos in CI, currently for compiler only (to reduce commit size with fixes). With current setup, exclude list is quite short, so it worth trying?
Also includes commits with actual typo fixes.
MCP: https://github.com/rust-lang/compiler-team/issues/817
typos check currently turned for:
* ./compiler
* ./library
* ./src/bootstrap
* ./src/librustdoc
After merging, PRs which enables checks for other crates (tools) can be implemented too.
Found typos will **not break** other jobs immediately: (tests, building compiler for perf run). Job will be marked as red on completion in ~ 20 secs, so you will not forget to fix it whenever you want, before merging pr.
Check typos: `python x.py test tidy --extra-checks=spellcheck`
Apply typo fixes: `python x.py test tidy --extra-checks=spellcheck:fix` (in case if there only 1 suggestion of each typo)
Current fail in this pr is expected and shows how typo errors emitted. Commit with error will be removed after r+.
Lazy-ify some markdown rendering
Seems to have a positive effect in my local perf runs 😍

Rename `mingw-*` CI jobs to `pr-*`
The name `mingw` confuses people because these CI jobs now do much more than just cross-compile to mingw.
This is basically a find/replace. I chose the name `pr-` because it's job is to do general PR checks,
miri: improve errors for type validity assertion failures
Miri has pretty nice errors for type validity violations, printing which field in the type the problem occurs at and so on.
However, we don't see these errors when using e.g. `mem::zeroed` as that uses `assert_zero_valid` to bail out before Miri can detect the UB.
Similar to what we did with `@saethlin's` UB checks, I think we should disable such language UB checks in Miri so that we can get better error messages. If we go for this we should probably say this in the intrinsic docs as well so that people don't think they can rely on these intrinsics catching anything.
Furthermore, I slightly changed `MaybeUninit::assume_init` so that the `.value` field does not show up in error messages any more.
`@rust-lang/miri` what do you think?
interpret: move the native call preparation logic into Miri
`@nia-e` has to do a bunch of changes to this logic for her native call ptrace work, and it's getting annoying that the logic is split between Miri and rustc. So this moves the logic to Miri, keeping just the generic traversal part in rustc. It is unfortunate that this means we have to expose `get_alloc_raw`/`get_alloc_raw_mut`... I hope the function name is scary enough to reduce the risk of misuse.

Add bootstrap check snapshot tests
Split off from https://github.com/rust-lang/rust/pull/143048, so that we get a baseline of how check behaved before we make changes to it. Note that the output of the check snapshot tests is suboptimal in many places, as we're missing information about stages and the build compiler. That will be changed in https://github.com/rust-lang/rust/pull/143048.

Explicitly handle all nodes in `generics_of` when computing parent
If we, for example, forget to feed `generics_of` then it'll silently fall back to empty generics. Make this a bit more explicit.
Make the enum check work for negative discriminants
The discriminant check was not working correctly for negative numbers. This change fixes that by masking out the relevant bits correctly.
Fixesrust-lang/rust#143218.
