[docs] Update armv6k-nintendo-3ds platform docs for outdated info
Mostly just fixing links and references to renamed crates, but also updating a bit of outdated info as well.

Assert that params with the same *index* have the same *name*
Found this bug when trying to build libcore with the new solver, since it will canonicalize two params with the same index into *different* placeholders if those params differ by name.
always run `configure_linker` except for mir-opt tests
`configure_linker` now runs consistently unless it's for mir-opt tests. Previously `!= "check"` condition was causing dirt in the cargo cache between runs of `x anything-but-not-check` and `x check`.

Suggest pattern tests when modifying exhaustiveness
The vast majority of exhaustiveness tests are in `tests/ui/pattern`, this is what I've been using for years. This PR is me telling `x suggest` about that.

Update mdbook to 0.4.37
This updates mdbook to 0.4.37.
Changelog: https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-0437
The primary change is the update to pulldown-cmark which has a large number of markdown parsing changes. There shouldn't be any significant changes to the rendering of any of the books (I have posted some PRs to fix some minor issues to the ones that were affected).
core: add Duration constructors
Add more `Duration` constructors.
Tracking issue: #120301.
These match similar convenience constructors available on both `chrono::Duration` and `time::Duration`.
What's the best ordering for these with respect to the existing constructors?
Allowing the Xcode version to "float" based on whatever default GitHub
selects creates an unreliable environment. When GitHub changes the
default, we can have multiple jobs in the same run using different
versions as it rolls out across machines. It can also cause oscillation
between runs as different machines are used. It also causes
unpredictable timing when the updates happen.
This change helps ensure that the version that is used is pinned. The
downside is that it requires manually bumping the version, and the risk
that if we take too long, older Xcodes will be removed and that will
break the build.
This seems to fix two sporadic errors that have been appearing in CI.
One is an issue with cmake being unable to verify that cmake is able to
build a simple test program. The other is a `invalid r_symbolnum`
linking error when trying to build one of cranelift's tests.
This is intended as a temporary fix until we can figure out how to
resolve those issues.
Adapt `llvm-has-rust-patches` validation to take `llvm-config` into account.
This adapts an assertion that was added in #119556.
The current assertion does not take the `llvm-config` setting into accounts, which does not match the `llvm-has-rust-patches` documentation, which states:
> This would be used in conjunction with either an llvm-config or build.submodules = false.
(It also breaks my workflow: I build LLVM separately, but do have the rust patches applied).
---
**edit:** Originally this PR just removed the assertion, but it now implements the alternative mentioned here:
An alternative fix would be to take `llvm-config` into account in the assertion, but to me the assertion seems to provide little value, thus the simpler fix of just removing it.
cc `@onur-ozkan,` in case I'm missing a reason to keep the assertion.
fix `llvm_out` to use the correct LLVM root
When `download-ci-llvm` is enabled, `llvm_out` ends up with the
error below due to an incorrect path on cross-compilations. This change fixes that.
```sh
failed to execute command: "/rust/build/x86_64-unknown-linux-gnu/llvm/build/bin/llvm-config" "--version"
ERROR: No such file or directory (os error 2)
```
[rustdoc] Correctly generate path for non-local items in source code pages
While browsing some crates using the "jump to def" feature, I realized that a lot of items didn't have a link generated. The reason is because we only cache foreign items if they appear in the documented API. This means that for the others, we need to infer them.

Startup objects disappearing from sysroot
When launching tests with --keep-stage option, startup objects such as rsbegin.o an rsend.o may disappear from the corresponding stageN compiler.
Fix issue #120784
Invert diagnostic lints.
That is, change `diagnostic_outside_of_impl` and `untranslatable_diagnostic` from `allow` to `deny`, because more than half of the compiler has been converted to use translated diagnostics.
This commit removes more `deny` attributes than it adds `allow` attributes, which proves that this change is warranted.

Toggle assert_unsafe_precondition in codegen instead of expansion
The goal of this PR is to make some of the unsafe precondition checks in the standard library available in debug builds. Some UI tests are included to verify that it does that.
The diff is large, but most of it is blessing mir-opt tests and I've also split up this PR so it can be reviewed commit-by-commit.
This PR:
1. Adds a new intrinsic, `debug_assertions` which is lowered to a new MIR NullOp, and only to a constant after monomorphization
2. Rewrites `assume_unsafe_precondition` to check the new intrinsic, and be monomorphic.
3. Skips codegen of the `assume` intrinsic in unoptimized builds, because that was silly before but with these checks it's *very* silly
4. The checks with the most overhead are `ptr::read`/`ptr::write` and `NonNull::new_unchecked`. I've simply added `#[cfg(debug_assertions)]` to the checks for `ptr::read`/`ptr::write` because I was unable to come up with any (good) ideas for decreasing their impact. But for `NonNull::new_unchecked` I found that the majority of callers can use a different function, often a safe one.
Yes, this PR slows down the compile time of some programs. But in our benchmark suite it's never more than 1% icount, and the average icount change in debug-full programs is 0.22%. I think that is acceptable for such an improvement in developer experience.

Fix issue #120784
The existing regex-based HTML parsing was just too primitive to
correctly handle HTML content. Some books have legitimate `href="…"`
text which should not be validated because it is part of the text, not
actual HTML.
`configure_linker` now runs consistently unless it's for mir-opt tests.
Previously `!= "check"` condition was causing dirt in the cargo cache between
runs of `x anything-but-not-check` and `x check`
