c2b564557d By default
Guessing Game states that "Rust only imports a few things into every
program, the ‘prelude’". That isn't strictly true.  That is all it
imports by default and the change clarifies that point.

247a0d1854 Auto merge of #27153 - alexcrichton:flaky-tests, r=brson
This commit ensures that the rustc thread does not leak a panic message whenever
a call to `fatal` happens. This already happens for the main rustc thread as
part of the `rustc_driver::monitor` function, but the compiler also spawns
threads for other operations like `-C codegen-units`, and sometimes errors are
emitted on these threads as well. To ensure that there's a consistent
error-handling experience across threads this unifies these two to never print
the panic message in the case of a normal and expected fatal error.

This should also fix the flaky `asm-src-loc-codegen-units.rs` test as the output
is sometimes garbled if diagnostics are printed while the panic message is also
being printed.

48a1f1b96f Auto merge of #27139 - pnkfelix:allow-disable-debuginfo, r=dotdash
fix `configure`: allow both `--enable-debug` and `--disable-debuginfo` in one invocation.

This is my very local fix to allow one to be able to (1.) build `rustc` and (2.) run `make check` with internal debug-mode *assertions* turned on in the presence of bugs like  #26447 and #26484 (both of which are solely caused by debuginfo and thus can be sidestepped via `--disable-debuginfo`).

This partially addresses #24416 (namely, it addresses the papercut outlined in the description of that ticket).  But there are other issues mentioned in the comment thread that are not addressed here, so they should be separately addressed before closing that ticket, or separate bugs should be opened for them.

238765e1eb Auto merge of #27103 - wthrowe:doc_format, r=alexcrichton
This fixes a couple of bugs visible on https://doc.rust-lang.org/nightly/std/marker/trait.Sync.html .  For example:
* `impl<T> Sync for *const T` should read `impl<T> !Sync for *const T`
* `impl<T> !Sync for Weak<T>` should read `impl<T> !Sync for Weak<T> where T: ?Sized`

This does change a struct in librustdoc and it seems that almost everything there is marked public, so if librustdoc has stability guarantees that could be a problem.  If it is, I'll find a way to rework the change to avoid modifying public structures.

118a5c4c34 Auto merge of #27129 - arthurprs:debug_atomic, r=alexcrichton
I'm being constantly bitten by the lack of this implementation.

I'm unsure if there's a reason to avoid these implementations though.

Since we have a "lossy" implementation for both Mutex and RWLock (RWLock {{ locked }}) I don't think there's a big reason for not having a Debug implementation for the atomic types, even if the user can't specify the ordering.

a41178e858 Auto merge of #27110 - arthurprs:optintstr, r=Gankro
I wrote a reasonably optimized version for both functions. Further optimizations are possible but I tried to keep the code size small (which I think is important), it's a road of diminished gains.

The repository used for testing/benchmarks is https://github.com/arthurprs/rust-optimized-inttostr

Benchmarks are ran for 3 different distributions, bellow are string length histograms for the u32 type

* _h (big numbers skew)
[0, 0, 5, 29, 103, 212, 551, 1138, 1887, 3196, 2879]
* _m (slight small number skew):
[0, 2807, 1334, 1057, 905, 821, 772, 707, 627, 605, 365]
* _l (small numbers skew):
[0, 8004, 567, 351, 248, 212, 170, 126, 136, 112, 74]

Tested processors are
* x64 laptop (i7-2670QM)
* x32 server (Digital Ocean E5-2630L-v2)

### Display

It uses a small look up table (200 bytes) and decode up to 4 characters at a time. I also took special precautions to reduce 64bit arithmetic on 32bit architectures and the gains are huge in these cases.

Overall, on modern 64bit CPUs it's pretty much the same speed as the stdlib implementation for very small numbers (0..99), but pulls ahead as the length of the decimal increases. On slight older CPUs (w/ worse ALUs) or 32bit architectures it's pretty much always faster.

All valid digits are ascii so I modified the function to use the underlining bytes instead and simplified the match to avoid wasting cycles.
