Do not accidentally treat multi-segment meta-items as single-segment
Fixes https://github.com/rust-lang/rust/issues/55168 and many other regressions from https://github.com/rust-lang/rust/pull/50030
Basically, attributes like `#[any::prefix::foo]` were commonly interpreted as `#[foo]` due to `name()` successfully returning the last segment (this applies to nested things as well `#[attr(any::prefix::foo)]`).
This should make it easier to identify what each job is doing when looking at the Travis or Appveyor UI.
- Set `name` for each job in Travis.
- Move `CI_JOB_NAME` to the front in Appveyor so that it appears first in the UI.

Option and Result: Add references to documentation of as_ref and as_mut
This makes the documentation more consistent with that of `Pin::as_ref` which converts "from `&Pin<Pointer<T>>` to `Pin<&t>`".
This generally makes it clearer that the reference is going inside the option.
Remove restriction on isize/usize in repr(simd)
As discussed in #55078, there's no known reason for this restriction.
It's unlikely that repr(simd) will be stabilized in its current form, but
might as well remove some restrictions on it.
This removes the branch in `is_machine` which returns false for these types.
`is_machine` is only used for the repr(simd) type validation check.
No old chestnuts in iter::repeat docs
The current language may be amusing, yet is just imprecise and most especially difficult to understand for someone who speaks English as a foreign language.
bootstrap: Default to a sensible llvm-suffix.
I used version-channel-sha, hopefully that should work.
I checked that bootstrap builds, but I cannot check anything else since the llvm
build process is started from cargo, and thus calls clang, and thus I hit the
same bug I hope to fix with this change.
Hopefully fixes#59034.
Add `-Z allow_features=...` flag
Adds a compiler option to allow only whitelisted features.
For projects on nightly that want to prevent feature-creep (and maybe, someday, move off of nightly). Not being able to enforce this has been a problem on Fuchsia and at other big companies.
This doesn't support filtering edition feature flags, but someone is welcome to add that if they need it.
Revert "Don't generate minification variable if minification disabled"
Reverts #58643Fixes#59157https://github.com/rust-lang/rust/pull/58643 made us stop generating minification variables when minification is disabled, however they may still be needed for parent crates that were generated with minification (this will always be the case for libstd and libcore)

[wg-async-await] Add regression test for #55809.
Fixes#55809.
This PR adds a regression test for #55809 which checks that a
overflow does not occur when evaluating a requirement for async
functions and `&mut` arguments in some specific circumstances.
Stabilize Range*::contains.
Closes https://github.com/rust-lang/rust/issues/32311. There's also a bit of rustfmt on range.rs thrown in for good measure (I forgot to turn off format-on-save in VSCode).
Make std time tests more robust for platform differences
Previously, `time::tests::since_epoch` and `time::tests::system_time_math` would fail if the platform represents a SystemTime as unix epoch + `u64` nanoseconds.

A few improvements to comments in user-facing crates
Not too many this time, and all concern comments (almost all doc comments) in user-facing crates (libstd, libcore, liballoc).

Avoid some common false positives in intra doc link checking
The empty string case is never going to be a link. The numeric case may be a link, but if it were it would have resolved locally. It's more likely the makeshift markdown footnote notation (`[0]`, etc)

Fix ICE in MIR pretty printing
A `Def::Variant` should be considered as a function in mir pretty
printing. Each variant has a constructor that we must print.
Given the following enum definition:
```rust
pub enum TestMe {
X(usize),
}
```
We will need to generate a constructor for the variant `X` with a
signature that looks something like the following:
```
fn TestMe::X(_1: usize) -> TestMe;
```
Fixes: #59021
Fix generic argument lookup for Self
Rewrite the SelfCtor early and use the replacement Def when
calculating the path_segs.
Note that this also changes which def is seen by the code that
computes user_self_ty and is_alias_variant_ctor; I don't see a
immediate issue with that, but I'm not 100% clear on the
implications.
Fixes#57924
