It is mostly for BSD system. Some tests (run-make/issue-35164 and
run-make/cat-and-grep-sanity-check) are failing with BSD
fgrep, whereas they pass with gnu version (gfgrep).

Try to bring back the `dist-i686-linux` and `dist-x86_64-linux alt` builders which has mysteriously lost their cache 14 hours ago and stuck forever unable to download `mpfr-2.4.2.tar.bz2` since it keeps getting
```
==> PASV ... couldn't connect to 209.132.180.131 port 10058: Connection timed out
```
Unfortunately we don't have sufficient time to rebuild the cache *and*
distribute everything in `dist-x86_64-linux alt`, the debug assertions are
really slow.
We will re-enable them after the PR has been successfully merged, thus
successfully updating the cache (freeing up 40 minutes), giving us enough
time to build these tools.
Fix ordering of auto-generated trait bounds in rustdoc output
While the order of the where clauses was deterministic, the
ordering of bounds and lifetimes was not. This made the order flip-
flop randomly when new traits and impls were added to libstd.
This PR makes the ordering of bounds and lifetimes deterministic,
and re-enables the test that was causing the issue.
Fixes#49123
This should fix regressions in Cargo after swithing to clap:
* If an external subcommand name was close to built-in one, clap
errored (fixed by updating clap version)
* External subcomands didn't received their name as a first arg

config.toml.example: thinlto bootstrap was removed
It was removed in ff227c4a2d so remove the option that no longer works (we did not notice because it was commented out by default).
Add BufReader::buffer
This subsumes the need for an explicit is_empty function, and provides
access to the buffered data itself which has been requested from time to
time.
We could call this `buf` to match `fill_buf`, but I think I'd prefer `fill_buffer` anyways in hindsight.
rustbuild: Ship libsynchronization
Hot on the heels of #49044 comes similar issue with libsynchronization. Discovered while building clippy:
```
<skipped>
Compiling serde_derive v1.0.33
error: linking with `gcc` failed: exit code: 1
<skipped>
= note: ld: cannot find -lsynchronization
```

Suggest removing `&`s
This implements the error message discussed in #47744.
We check whether removing each `&` yields a type that satisfies the requested obligation.
Also, it was created a new `NodeId` field in `ObligationCause` in order to iterate through the `&`s. The way it's implemented now, it iterates through the obligation snippet and counts the number of `&`.

Implement Integer methods for Wrapping
Wrapping<T> now implements:
count_ones, count_zeros, leading_zeros,
trailing_zeros, rotate_left, rotate_right, swap_bytes, from_be,
from_le, to_be, to_le, and pow
where T is:
u8, u16, u32, u64, usize, i8, i16, i32, i64, or isize.
Docs were written for all these methods, as well as examples. The
examples mirror the ones on u8, u16, etc... for consistency.
Closes#32463
Improve documentation for Borrow
This is the first step in improving the documentation for all the reference conversion traits. It proposes new text for the trait documentation of `Borrow`. Since I feel it is a somewhat radical rewrite and includes a stricter contract for `Borrow` then the previous text—namely that *all* shared traits need to behave the same, not just a select few—, I wanted to get some feedback before continuing.
Apart from the ‘normative’ description, the new text also includes a fairly extensive explanation of how the trait is used in the examples section. I included it because every time I look at how `HashMap` uses the trait, I need to think for a while as the use is a bit twisted. So, I thought having this thinking written down as part of the trait itself might be useful. One could argue that this should go into The Book, and, while I really like having everything important in the docs, I can see the text moved there, too.
So, before I move on: is this new text any good? Do we feel it is correct, useful, comprehensive, and understandable?
(This PR is in response to #44868 and #24140.)

we really need tests for this. do we have any cross compilation tests? I couldn't find any
