Drop panic hook after running tests
Issue: https://github.com/rust-lang/rust/issues/119223
Previously we left the panic hook we allocated
on main termination. Doing so makes Valgrind
report it as a reachable unfreed block.
In order to fix that use `panic::take_hook()` before examining test results.
Example backtrace:

Simplify/cleanup `search-result-color.goml`
Greatly shorten code of `search-result-color.goml` GUI test.
I split the changes into smaller commits to allow to more easily see what changed.
r? `@notriddle`
Add missing -Zquery-dep-graph to the spike-neg incr comp tests
This ensures that the tests actually test what they are meant to test rather than exitting immediately with an error that -Zquery-dep-graph has to be passed.
optimize tidy check on `src/tools/tidy/src/issues.txt`
This change applies to the following:
- Handles `is_sorted` in the first iteration without needing a second.
- Fixes line sorting on `--bless`.
- Reads `issues.txt` as str rather than making it part of the source code.
Fixes#123002
This sharding is never used (per the comment in code). If we re-add
sharding at some point in the future this is cheap to restore, but for
now no need for the extra complexity.
This ensures that the tests actually test what they are meant to test
rather than exitting immediately with an error that -Zquery-dep-graph
has to be passed.

bootstrap: split cargo-miri test into separate Step
This makes it easier to test just the driver or the cargo-miri integration.
````@rust-lang/miri```` this means to test both you now need to do `./x.py test miri cargo-miri`.

I'm trying to understand the process for such proposal. And I'll appreciate it if anyone can guide me the next step for consensus or adding tests.

CFI: Don't rewrite ty::Dynamic directly
Now that we're using a type folder, the arguments in predicates are processed automatically - we don't need to descend manually.
We also want to keep projection clauses around, and this does so.

Improve cfg and check-cfg configuration
This PR improves cfg and check-cfg configuration by:
1. Extracting both logic under a common module (to improve the connection between the two)
2. Adding more documentation, in particular some steps when adding a new cfg
I also added my-self as mention in our triagebot conf for the new module.

MSVC targets should use COFF as their archive format
While adding support for Arm64EC I ran into an issue where the standard library's rlib was missing the "EC Symbol Table" which is required for the MSVC linker to find import library symbols (generated by Rust's `raw-dylib` feature) when building for EC.
The root cause of the issue is that LLVM only generated symbol tables (including the EC Symbol Table) if the `ArchiveKind` is `COFF`, but the MSVC targets didn't set their archive format, so it was defaulting to GNU.
Require LLVM_CONFIG to be set in rustc_llvm/build.rs
This environment variable should always be set by bootstrap in `rustc_llvm_env`. The fallback is quite ugly and complicated, so removing it is nice.
bf71daedc2/src/bootstrap/src/core/build_steps/compile.rs (L1166)
I tried finding when this was added in git history, but it pointed all the way to "add build scripts" at which point I stopped digging more. This has always been here.

Check def id before calling `match_projection_projections`
When I "inlined" `assemble_candidates_from_predicates` into `for_each_item_bound` in #120584, I forgot to copy over the check that actually made sure the def id of the candidate was equal to the def id of the obligation. This means that we normalize goal a bit too often even if it's not productive to do so.
This PR adds that def id check back.
Fixes#123448
