This caught several places which weren't waiting until the command finished to drop the Group.
I also took the liberty of calling `msg_sysroot_tool` from `run_cargo_test` to reduce code duplication and make errors like this less likely in the future.
This avoids the following broken logging in CI:
```
{"book":"test-pass","reference":"test-pass","rustbook":"test-fail","rust-by-example":"test-pass","nomicon":"test-pass","embedded-book":"test-pass","edition-guide":"test-pass"}::group::Building bootstrap
```
Print artifact sizes in `opt-dist`
The Python PGO script printed a nice table of artifact sizes (`librustc_driver.so`, `libLLVM.so`, ...) at the end of the CI run, which was useful to quickly see the sizes of important files. I forgot to port this functionality into the Rust (`opt-dist`) version in https://github.com/rust-lang/rust/pull/112235. This PR fixes that.

refactor(rustc_middle): Substs -> GenericArg
resolves#110793
- [x] rename `SubstsRef` and `InternalSubsts` to `GenericArgsRef<'tcx>` and `GenericArgs<'tcx>`.
- [x] rename variables and fields currently using `substs` to `args`.
- [x] update the module name of `ty::subst` to `ty::generic_args` or sth. Make that module private and publicly reexport its content in the ty module.
- [x] rename `EarlyBinder::subst(_identity)` to `EarlyBinder::instantiate(_identity)`.
- [x] types called `[a-zA-Z]+Substs` renamed to `XArgs`.
- [x] functions containing `substs` now use `args` or `generic_args` (mostly the former).
However, the verb of "substituting" is still being used here and there, mostly in comments. I think that can be a separate PR as part of https://github.com/rust-lang/rust/issues/110254 to change the verb to `replace_generics` or something similar.
Make `nodejs` control the default for RustdocJs tests instead of a hard-off switch
If someone says `x test rustdoc-js-std` explicitly on the command line, it's because they want to run the tests. Give an error instead of doing nothing and reporting success.
Before:
```
; x t rustdoc-js
No nodejs found, skipping "tests/rustdoc-js" tests
Build completed successfully in 0:00:00
```
After:
```
; x t rustdoc-js
thread 'main' panicked at 'need nodejs to run js-doc-test suite', test.rs:1566:13
Build completed unsuccessfully in 0:00:00
```
I recommend viewing the diff with whitespace changes disabled.

Add jump to doc
I'm using the source code pages of the compiler quite a lot, but one thing missing is the possibility to jump back from the source code to the item documentation. Since I also got a few others complaining about it, I think it's fine to add it since this option is nightly only.
This PR adds a link to jump back to item's documentation on the item definition (so on `Bar` in `struct Bar {... }`, as described in the unofficial [RFC](https://github.com/GuillaumeGomez/rfcs/blob/rustdoc-jump-to-definition/text/000-rustdoc-jump-to-definition.md)).

Fix bootstrap.py uname error
The x.py script fails with `ValueError: too many values to unpack (expected 3)` when uname -smp gives more than 3 words
The error I got:
```
❯ ./x check
Traceback (most recent call last):

This is because

Returns more than 3 space separated words.
Allow to have `-` in rustdoc-json test file name
I extracted this commit from https://github.com/rust-lang/rust/pull/113574.
When I added the test, it kept saying that the JSON file couldn't be found. After investigating for a while, I discovered that we were expecting files to always use `_`, which is quite bad. So I added support for `-` in file names.

Test simd-wide-sum for codegen error
This adds the necessary test infrastructure to "build-pass" codegen tests, for the purpose of doing that for a single revision of a codegen test. When mir-opts are tested, the output may vary from the usual, and maybe for positive reasons... but we don't necessarily want to output such bad LLVMIR that LLVM starts crashing on it.
Currently when enabling MIR opts at higher levels this LLVMIR is still emitted, but it was previously disabled for getting in mir-opt's way and as this new revision without `// [mir-opt3]build-pass` would make it more likely to, I would like to not see the testing for the actual results regress again just because it was bundled with an ICE check as well.
This fixes https://github.com/rust-lang/rust/issues/98016

Implement selection for `Unsize` for better coercion behavior
In order for much of coercion to succeed, we need to be able to deal with partial ambiguity of `Unsize` traits during selection. However, I pessimistically implemented selection in the new trait solver to just bail out with ambiguity if it was a built-in impl:
9227ff28af/compiler/rustc_trait_selection/src/solve/eval_ctxt/select.rs (L126)
This implements a proper "rematch" procedure for dealing with built-in `Unsize` goals, so that even if the goal is ambiguous, we are able to get nested obligations which are used in the coercion selection-like loop:
9227ff28af/compiler/rustc_hir_typeck/src/coercion.rs (L702)
Second commit just moves a `resolve_vars_if_possible` call to fix a bug where we weren't detecting a trait upcasting to occur.

Ignore flaky clippy tests.
These tests are frequently failing due to an issue in ui_test. ui_test doesn't appear to have a blanket ignore instruction that I could find, so I just approximated it with ignoring both 32 and 64 bit.

(re-)tighten sourceinfo span of adjustments in MIR
Diagnostics rely on the spans of MIR statements being (approximately) correct in order to give suggestions relative to that span (i.e. `shrink_to_hi` and `shrink_to_lo`).
I discovered that we're *intentionally* lowering THIR exprs with their parent expr's span if they come from adjustments that are due to a parent expression. While I understand why that may be desirable to demonstrate the relationship of an adjustment and the expression that requires it, it leads to
1. very verbose borrowck output
2. incorrect spans for suggestions
Some diagnostics get around that by giving suggestions relative to other spans we've collected during MIR lowering, such as the span of the method's identifier (e.g. `name` in `.name()`), but this doesn't work too well when things come from desugaring.
I assume it also has lead to numerous tweaks and complications to diagnostics code down the road, which this PR doesn't necessarily aim to fix but may open the gates to fixing later... The last three commits are simplifications due to the fact that we can assume that the move span actually points to what is being moved (and a test).
This regressed in #89110, which was debated somewhat in #90286. cc `@Aaron1011` who originally made this change.

miri: protect Move() function arguments during the call
This gives `Move` operands a meaning specific to function calls:
- for the duration of the call, the place the operand comes from is protected, making all read and write accesses insta-UB.
- the contents of that place are reset to `Uninit`, so looking at them again after the function returns, we cannot observe their contents
Turns out we can replace the existing "retag return place" hack with the exact same sort of protection on the return place, which is nicely symmetric.

This starts with a Miri rustc-push, since we'd otherwise conflict with a PR that recently landed in Miri.
(The "miri tree borrows" commit is an unrelated cleanup I noticed while doing the PR. I can remove it if you prefer.)
