Stop using specialization in rustc_index and rustc_borrowck
For rustc_borrowck the version with specialization isn't much more readable anyway IMO. For rustc_index it probably doesn't affect perf in any noticeable way anyway.
This makes it easier to use commands in a "Fluent-API" style, and also removes the need for the `AsMut` trait hack that
was used before to allow passing both `BootstrapCommand` and `&mut BootstrapCommand` to `Builder::run`.
The `Builder::run` method was still kept and can be used explicitly, if needed for some reason.
This patch adds a new lint that checks for potentially harder to read
byte char slices: `&[b'a', b'b']` and suggests to replace them with the
easier to read `b"ab"` form.

Bootstrap command refactoring: consolidate output modes (step 3)
This PR is a continuation to https://github.com/rust-lang/rust/pull/126731. It consolidates the output modes of bootstrap (`Print` vs `CaptureAll` vs `CaptureStdout`) and simplifies the logic around error printing (now a command error is always printed if the failure is not ignored). It also ports even more usages of `Command` to `BootstrapCommand`, most notably the git helpers and many usages of the `output` function.
The last commit was added because the third commit made two variants of the `Tool` enum unused (no idea why, but it seems to have been a false positive that they were used before).
It can be reviewed now, but I would wait with merging until at least a few days after https://github.com/rust-lang/rust/pull/126731, just to catch any potential issues from that PR before we move further.
As a next step, I want to clean up the API of the command a little bit to make usage easier (currently it's a bit verbose), and then continue with the rest of the tasks from the tracking issue.
As always, best reviewed commit by commit.

TB: Refine protector end semantics
Tree Borrows has protector end tag semantics, namely that protectors ending cause a [special implicit read](https://perso.crans.org/vanille/treebor/diff.0.html) on all locations protected by that protector that have actually been accessed. See also #3067.
While this is enough for ensuring protectors allow adding/reordering reads, it does not prove that one can reorder writes. For this, we need to make this stronger, by making this implicit read be a write in cases when there was a write to the location protected by that protector, i.e. if the permission is `Active`.
There is a test that shows why this behavior is necessary, see `tests/fail/tree_borrows/protector-write-lazy.rs`.

When dry run is enabled, the command for finding LLDB version would succeed, but return an empty string. This was inadvertently enabling a code path that should only be executed when the LLDB is actually present and its version is valid. This commit makes sure that if the version is empty, LLDB will be considered not found.
jsondocck: Use correct index for error message.
If you misused a count command like ``@count` $some.selector '"T'"`, you would panic with OOB:
```
thread 'main' panicked at src/tools/jsondocck/src/main.rs:76:92:
index out of bounds: the len is 2 but the index is 2
```
This is because 57c85bd97d removed the file param, but didn't update the error case. We now error with:
```
Invalid command: Second argument to `@count` must be a valid usize (got `"T"`) on line 20
```
As some point I want to rewrite this code to avoid indexing in general, but this is a nice small fix.

Remove unqualified form import of io::Error in process_vxworks.rs and fallback on remove_dir_impl for vxworks
Hi all,
This is to address issue #127084. On inspections it was found that io::Error refrences were all of qualified form and there was no need to add a unqualified form import. Also to successfully build rust for vxworks, we need to fallback on the remove_impl_dir implementations.
Thank you.
Add new lint `hashset_insert_after_contains`
This PR closes https://github.com/rust-lang/rust-clippy/issues/11103.
This is my first PR creating a new lint (and the second attempt of creating this PR, the first one I was not able to continue because of personal reasons). Thanks for the patience :)
The idea of the lint is to find insert in hashmanps inside if staments that are checking if the hashmap contains the same value that is being inserted. This is not necessary since you could simply call the insert and check for the bool returned if you still need the if statement.
