don't copy `.rustc-dev-contents` from CI rustc
Since https://github.com/rust-lang/rust/pull/127188, copying files from `.rustc-dev-contents` regressed https://github.com/rust-lang/rust/issues/108767 again. Since `rustc-src` is already included in the CI rustc sysroot, we don't need to copy these files to have `rustc-src` component.
Blocker for #122709

custom/external clippy support for bootstrapping
Similar to cargo, rustc, and rustfmt, this adds the support of using custom clippy on bootstrap. It’s designed for those who want to test their own clippy builds or avoid downloading the stage0 clippy.
Closes #121518

add `aarch64_unknown_nto_qnx700` target - QNX 7.0 support for aarch64le
This backports the QNX 7.1 aarch64 implementation to 7.0.
* [x] required `-lregex` disabled, see https://github.com/rust-lang/libc/pull/3775 (released in libc 0.2.156)
* [x] uses `libgcc.a` instead of `libgcc_s.so` (7.0 used ancient GCC 5.4 which didn't have gcc_s)
* [x] a fix in `backtrace` crate to support stack traces https://github.com/rust-lang/backtrace-rs/pull/648
This PR bumps libc dependency to 0.2.158

# Configure a remote for testing
Do this from a new shell - we will need to run more commands in the previous one. I ran into these two issues, and found some workarounds.
* Temporary dir might not work properly
* Default `remote-test-server` has issues binding to an address
```

starting test server
thread 'main' panicked at src/tools/remote-test-server/src/main.rs:175:29:

Specifying `--bind` param actually fixes that, and so does setting `TMPDIR` properly.

Enable Miri to pass pointers through FFI
Following https://github.com/rust-lang/rust/pull/126787, the purpose of this PR is to now enable Miri to execute native calls that make use of pointers.
> <details>
>
> <summary> Simple example </summary>
>
> ```rust
> extern "C" {
> fn ptr_printer(ptr: *mut i32);
> }
>
> fn main() {
> let ptr = &mut 42 as *mut i32;
> unsafe {
> ptr_printer(ptr);
> }
> }
> ```
> ```c
> void ptr_printer(int *ptr) {
> printf("printing pointer dereference from C: %d\n", *ptr);
> }
> ```
> should now show `printing pointer dereference from C: 42`.
>
> </details>
Note that this PR does not yet implement any logic involved in updating Miri's "analysis" state (byte initialization, provenance) upon such a native call.

skip stage 0 target check if `BOOTSTRAP_SKIP_TARGET_SANITY` is set
When adding a new target to `rustc` and extending `STAGE0_MISSING_TARGETS`, there is a chance that in the merge CI bootstrap target sanity check might fail [here](https://github.com/rust-lang/rust/blob/26d27b7c8729fb61fe8321fcd2ce734a79aa695d/src/bootstrap/src/core/sanity.rs#L243-L256) because the stage 0 compiler will assume to already support the new target since `opt-dist` uses the previously compiled compiler as the stage 0 compiler.
This PR skips this check if `BOOTSTRAP_SKIP_TARGET_SANITY` is set, and makes `opt-dist` to set `BOOTSTRAP_SKIP_TARGET_SANITY` so bootstrap doesn't run this logic for opt-dist tests.
Fixes https://github.com/rust-lang/rust/pull/127021#issuecomment-2308782315.

Add missing `needs-llvm-components` directives for run-make tests that need target-specific codegen
Without suitable `needs-llvm-components` directives, some run-make tests exercising target-specific codegen can fail if the LLVM used is built without the necessary components. Currently, the list is:
```
tests\run-make\print-target-list
tests\run-make\print-to-output
tests\run-make\print-cfg
tests\run-make\target-without-atomic-cas
```
This PR also skips tidy checks for revisions and `needs-llvm-components` for run-make tests since revisions are not supported.
Fixes #129390.
Fixes #127895.
cc ``@petrochenkov`` who noticed this, thanks! Would be great if you could confirm that this fixes the test errors for you locally.

Expand NLL MIR dumps
This PR is a first step to clean up and expand NLL MIR dumps:
- by restoring the "mir-include-spans" comments which are useful for `-Zdump-mir=nll`
- by adding the list of borrows to NLL MIR dumps, where they are introduced in the CFG and in which region
Comments in MIR dumps were turned off in #112346, but as shown in #114652 they were still useful for us working with NLL MIR dumps. So this PR pulls `-Z mir-include-spans` into its own options struct, so that passes dumping MIR can override them if need be. The rest of the compiler is not affected, only the "nll" pass dumps have these comments enabled again. The CLI still has priority when specifying the flag, so that we can explicitly turn them off in the `mir-opt` tests to keep blessed dumps easier to work with (which was one of the points of #112346).
Then, as part of a couple steps to improve NLL/polonius MIR dumps and `.dot` visualizations, I've also added the list of borrows and where they're introduced. I'm doing all this to help debug some polonius scope issues in my prototype location-sensitive analysis :3. I'll probably add member constraints soon.

interpret/visitor: make memory order iteration slightly more efficient
Finally I know enough about RPIT to write this iterator signature correctly. :D
This means memory-order iteration now needs an allocation, but it avoids quadratic complexity (where it has to do a linear scan n times to find the n-th field in memory order), so that seems like a win overall. The changed code only affects Miri; the rustc changes are NOPs.

Stop using `ty::GenericPredicates` for non-predicates_of queries
`GenericPredicates` is a struct of several parts: A list of of an item's own predicates, and a parent def id (and some effects related stuff, but ignore that since it's kinda irrelevant). When instantiating these generic predicates, it calls `predicates_of` on the parent and instantiates its predicates, and appends the item's own instantiated predicates too:
https://github.com/rust-lang/rust/blob/acb4e8b6251f1d8da36f08e7a70fa23fc581839e/compiler/rustc_middle/src/ty/generics.rs#L407-L413
Notice how this should result in a recursive set of calls to `predicates_of`... However, `GenericPredicates` is *also* misused by a bunch of *other* queries as a convenient way of passing around a list of predicates. For these queries, we don't ever set the parent def id of the `GenericPredicates`, but if we did, then this would be very easy to mistakenly call `predicates_of` instead of some other intended parent query.
Given that footgun, and the fact that we don't ever even *use* the parent def id in the `GenericPredicates` returned from queries like `explicit_super_predicates_of`, It really has no benefit over just returning `&'tcx [(Clause<'tcx>, Span)]`.
This PR additionally opts to wrap the results of `EarlyBinder`, as we've tended to use that in the return type of these kinds of queries to properly convey that the user has params to deal with, and it also gives a convenient way of iterating over a slice of things after instantiating.

Separate core search logic with search ui
Currenty, the `search.js` mixed with UI/DOM manipulation codes and search logic codes, I propose to extract the search logic to a class for following benefits:
- Clean code. Separation of DOM manipulation and search logic can lead better code maintainability and easy code testings.
- Easy share the search logic for third party to utilize the search function, such as [Rust Search Extension](https://rust.extension.sh), https://query.rs.
This PR added a new class called `DocSearch`, which mainly expose following methods:
```js
class DocSearch {
// Dependency inject searchIndex, rootPath and searchState
constructor(rawSearchIndex, rootPath, searchState) {
// build search index...
}
static parseQuery(userQuery) {
}
async execQuery(parsedQuery, filterCrates, currentCrate) {
}
}
```

Try to reduce space usage in dist CI
We have had recurrent CI problems as a result of GitHub adding a new version of Xcode to its runners[^0], which has consumed ~40GB of space which served as padding. Try to reduce the number of Xcodes on our systems, because we only use Xcode 14 in actual practice. Also, try to move files instead of pointlessly copy them when we're at the end of the job.
I could not resist addressing a few shellcheck lints while I was at it.
