When spawning Commands, the path we use can end up being queried using `env::current_exe` (or the equivalent in other languages). Not all applications handle these paths properly therefore we should have a stronger preference for non-verbatim paths when spawning processes.

Behind the scenes Clippy uses compiletest-rs, which doesn't support the
--json flag we added to Rust's compiletest.

Document `Iterator::sum/product` for Option/Result

Closes rust-lang#105266

We already document the similar behavior for `collect()` so I believe it makes sense to add this too. The Option/Result implementations *are* documented on their respective pages and the page for `Sum`, but buried amongst many other trait impls which doesn't make it very discoverable.

Include executed tests in the build metrics (and use a custom test display impl)

The main goal of this PR is to include all tests executed in CI inside the build metrics JSON files. I need this for Ferrocene, and ``@Mark-Simulacrum`` expressed desire to have this as well to ensure all tests are executed at least once somewhere in CI.

Unfortunately implementing this required rewriting inside of bootstrap all of the code to render the test output to console. libtest supports outputting JSON instead of raw text, which we can indeed use to populate the build metrics. Doing that suppresses the console output though, and compared to rustc and Cargo the console output is not included as a JSON field.

Because of that, this PR had to reimplement both the "pretty" format (one test per line, with `rust.verbose-tests = true`), and the "terse" format (the wall of dots, with `rust.verbose-tests = false`). The current implementation should have the exact same output as libtest, except for the benchmark output. libtest's benchmark output is broken in the "terse" format, so since that's our default I slightly improved how it's rendered.

Also, to bring parity with libtest I had to introduce support for coloring output from bootstrap, using the same dependencies `annotate-snippets` uses. It's now possible to use `builder.color_for_stdout(Color::Red, "text")` and `builder.color_for_stderr(Color::Green, "text")` across all of bootstrap, automatically respecting the `--color` flag and whether the stream is a terminal or not.

I recommend reviewing the PR commit-by-commit.

new solver: make all goal evaluation able to be automatically rerun

It is generally wrong to call `evaluate_goal` multiple times or `evaluate_goal` and `evaluate_all` for the same `QueryResult` without correctly handling rerunning the goals when inference makes progress. Not doing so will result in the assertion in `evaluate_goal` firing because rerunning the goal will lead to a more accurate `QueryResult`.

Currently there are lots of places that get this wrong and generally it is complex and error prone to handle correctly everywhere. This PR introduces a way to add goals to the `EvalCtxt` and then run all the added goals in a loop so that `evaluate_goal`/`evaluate_all` is not necessary to call manually.

There are a few complications for making everything work "right":
1. the `normalizes-to` hack that replaces the rhs with an unconstrained infer var requires special casing in the new `try_evaluate_added_goals` function similar to how `evaluate_goal`'s assertion special cases that hack.

2. `assemble_candidates_after_normalizing_self_ty`'s normalization step needs to be reran for each candidate otherwise the found candidates will potentially get a more accurate `QueryResult` when rerunning the projection/trait goal which can effect the `QueryResult` of the projection/trait goal.
This is implemented via `EvalCtxt::probe`'s closure's `EvalCtxt` inheriting the added goals of the `EvalCtxt` that `probe` is called on, allowing us to add goals in a probe, and then enter a nested probe for each candidate and evaluate added goals which include the normalization step's goals.

I made `make_canonical_response` evaluate added goals so that it will be hard to mess up the impl of the solver by forgetting to evaluate added goals. Right now the only way to mess this up would be to call `response_no_constraints` (which from the name is obviously weird).

The visibility of `evaluate_goal` means that it can be called from various `compute_x_goal` or candidate assembly functions, this is generally wrong and we should never call `evaluate_goal` manually, instead we should be calling `add_goal`/`add_goals`. This is solved by moving `evaluate_goal` `evaluate_canonical_goal` and `compute_goal` into `eval_ctxt`'s module and making them private so they cannot be called from elsewhere, forcing people to call `add_goal/s` and `evaluate_added_goals_and_make_canonical_resposne`/`try_evaluate_added_goals`

---

Other changes:
- removed the `&& false` that was introduced to the assertion in `evaluate_goal` in rust-lang#108839
- remove a `!self.did_overflow()` requirement in `search_graph.is_empty()` which causes goals that overflow to ICE
- made `EvalCtxt::eq` take `&mut self` and add all the nested goals via `add_goals` instead of returning them as 99% of call sites just immediately called `EvalCtxt::add_goals` manually.

Add `dist.compression-profile` option to control compression speed

PR rust-lang#108534 reduced the size of compressed archives, but (as expected) it also resulted in way longer compression times and memory usage during compression.

It's desirable to keep status quo (smaller archives but more CI usage), but it should also be configurable so that downstream users don't have to waste that much time on CI. As a data point, this resulted in doubling the time of Ferrocene's dist jobs, and required us to increase the RAM allocation for one of such jobs.

This PR adds a new `config.toml` setting, `dist.compression-profile`. The values can be:

* `fast`: equivalent to the gzip and xz preset of "1"
* `balanced`: equivalent to the gzip and xz preset of "6" (the CLI defaults as far as I'm aware)
* `best`: equivalent to the gzip present of "9", and our custom xz profile

The default has also been moved back to `balanced`, to try and avoid the compression time regression for downstream users. I don't feel too strongly on the default, and I'm open to changing it.

Also, for the `best` profile the XZ settings do not match the "9" preset used by the CLI, and it might be confusing. Should we create a `custom-rustc-ci`/`ultra` profile for that?

not *all* retags might be explicit in Runtime MIR

In rust-lang#105317 I made Miri treat `Rvalue::Ref/AddrOf` as implicit retagging sites. This updates the MIR docs accordingly.

For `Rvalue::Ref` I think this makes a lot more sense: creating a new reference is their entire point, so we can avoid bloating the MIR with retags. Also this seems to be the best way to handle cases like `*ptr = &[mut] ...`, where doing a retag is somewhat questionable since maybe `*ptr` points to another place now?

For `Rvalue::AddrOf`, Stacked Borrows needs this because even raw ptrs need some retagging, but Tree Borrows doesn't do ant retagging here and I hope we'll end up with a model where raw pointers don't get retagged.
