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.

rustdoc: update to pulldown-cmark 0.11
r? rustdoc
This pull request updates rustdoc to the latest version of pulldown-cmark. Along with adding new markdown extensions (which this PR doesn't enable), the new pulldown-cmark version also fixes a large number of bugs. Because all text files successfully parse as markdown, these bugfixes change the output, which can break people's existing docs.
A crater run, https://github.com/rust-lang/rust/pull/121659, has already been run for this change.
The first commit upgrades and fixes rustdoc. The second commit adds a lint for the footnote and block quote parser changes, which break the largest numbers of docs in the Crater run. The strikethrough change was mitigated in pulldown-cmark itself.

Make mtime of reproducible tarballs dependent on git commit
Since https://github.com/rust-lang/rust/pull/123246, our tarballs should be fully reproducible. That means that the mtime of all files and directories in the tarballs is set to the date of the first Rust commit (from 2006). However, this is causing some mtime invalidation issues (https://github.com/rust-lang/rust/issues/125578#issuecomment-2141068906).
Ideally, we would like to keep the mtime reproducible, but still update it with new versions of Rust. That's what this PR does. It modifies the tarball installer bootstrap invocation so that if the current rustc directory is managed by git, we will set the UTC timestamp of the latest commit as the mtime for all files in the archive. This means that the archive should be still fully reproducible from a given commit SHA, but it will also be changed with new beta bumps and `download-rustc` versions.
Note that only files are set to this mtime, directories are still set to the year 2006, because the `tar` library used by `rust-installer` doesn't allow us to selectively override mtime for directories (or at least I haven't found it). We could work around that by doing all the mtime modifications in bootstrap, but that would require more changes. I think/hope that just modifying the file mtimes should be enough. It should at least fix cargo `rustc` mtime invalidation.

Re-implement a type-size based limit
r? lcnr
This PR reintroduces the type length limit added in #37789, which was accidentally made practically useless by the caching changes to `Ty::walk` in #72412, which caused the `walk` function to no longer walk over identical elements.
Hitting this length limit is not fatal unless we are in codegen -- so it shouldn't affect passes like the mir inliner which creates potentially very large types (which we observed, for example, when the new trait solver compiles `itertools` in `--release` mode).
This also increases the type length limit from `1048576 == 2 ** 20` to `2 ** 24`, which covers all of the code that can be reached with craterbot-check. Individual crates can increase the length limit further if desired.
Perf regression is mild and I think we should accept it -- reinstating this limit is important for the new trait solver and to make sure we don't accidentally hit more type-size related regressions in the future.

Give remote-test-client a longer timeout
In https://github.com/rust-lang/rust/pull/126959, ``@Mark-Simulacrum`` suggested we simply extend the timeout of the `remote-test-client` instead of making it configurable. This is acceptable for my use case.
I'm doing some work with a remote host running tests using `x.py`'s remote test runner system.
After building the `remote-test-server` with:
```bash
./x build src/tools/remote-test-server --target aarch64-unknown-linux-gnu
```
I can transfer the `remote-test-server` to the remote and set up a port forwarded SSH connection, then I run:
```bash
TEST_DEVICE_ADDR=127.0.0.1:12345 ./x.py test library/core --target aarch64-unknown-linux-gnu
```
This works great if the host is nearby, however if the average round trip time is over 100ms (the timeout), it creates problems as it silently trips the timeout.
This PR extends that timeout to a less strict 2s.

Fix `FnMut::call_mut`/`Fn::call` shim for async closures that capture references
I adjusted async closures to be able to implement `Fn` and `FnMut` *even if* they capture references, as long as those references did not need to borrow data from the closure captures themselves. See #125259.
However, when I did this, I didn't actually relax an assertion in the `build_construct_coroutine_by_move_shim` shim code, which builds the `Fn`/`FnMut`/`FnOnce` implementations for async closures. Therefore, if we actually tried to *call* `FnMut`/`Fn` on async closures, it would ICE.
This PR adjusts this assertion to ensure that we only capture immutable references in closures if they implement `Fn`/`FnMut`. It also adds a bunch of tests and makes more of the async-closure tests into `build-pass` since we often care about these tests actually generating the right closure shims and stuff. I think it might be excessive to *always* use build-pass here, but 🤷 it's not that big of a deal.

Implement `x perf` as a separate tool
Continues work from https://github.com/rust-lang/rust/pull/126318, adds a CLI for running `rustc-perf` profiling commands through a new `rustc-perf-wrapper` tool. The CLI is in a separate tool to enable experimentation outside of `bootstrap`.
This is probably most of what we can do so far, I'll add support for benchmarking once `rustc-perf` gets a terminal output for comparing benchmark results.

The old error message was wrong (there is no `venv` Python package on PyPi), and we did not specify the correct Python path in the error message.
