This commit is an implementation of [RFC 1174][rfc] which adds three new traits
to the standard library:

* `IntoRawHandle` - implemented on Windows for files, processes, etc
* `IntoRawSocket` - implemented on Windows for networking types

9191a78955 Revert "Fix missing_docs lint for const and static." 
This reverts commit 00130cff99.

As mentioned in a regression report[1], this caused a notable amount
of breakage.  Because there's a plan to mitigate[2] this type of
breakage, I'm reverting this until then.

7cb157e74d Register new snapshots 
These new snapshots contain the knowledge of how to build the new triples of
32-bit MSVC and 32-bit FreeBSD, both of which should soon start having
nightlies/auto builders!

This does not currently register bitrig/freebsd snapshots but I believe those
will be retroactively added in the near future.

This commit fixes the negate_unsigned feature gate to appropriately

This is technically a [breaking-change], but I’d consider it a bug fix.

013d47b19b syntax: Suppress panic message on fatal 
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.

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.

### from_str_radix (FromStr)

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

And some other outdated language. @echochamber came asking about these docs
on IRC today, and they're a bit weird. I've updated them to be less ambiguous
and use contemporary terminology.

Per the title.  I've linked to the reference at http://doc.rust-lang.org/reference.html#type-parameters-1, but I'm not sure that's such a good link - but there doesn't seem to be a great deal of explanation elsewhere in the reference either...

It seems slightly more consistent to say 'Clones' here instead of 'Copies'. The docs for the `ToOwned` trait talk about cloning and not copying.
