The docs were making assertions/recommendations they shouldn't
have. This clarifies them and adds some helpful links.

Do not trigger unused_assignments for overloaded AssignOps
If `v` were a type with some kind of indirection, so that `v += 1` would
have an effect even if `v` were not used anymore, the unused_assignments lint
would mark a false positive.
This exempts overloaded (non-primitive) assign ops from being treated as
assignments (they are method calls).
The previous compile-fail tests that ensure x += 1 can trigger for
primitive types continue to pass. Added a representative test for the
"view" indirection.

These were intended to land in stable 1.8 but were just waiting for the
implementation PR, so now they're landing. Specifically this PR stabilizes:
* `AsciiExt::into_ascii_uppercase`
* `AsciiExt::into_ascii_lowercase`
* `AsciiExt for Vec<u8>`
* `AsciiExt for String`

This is mostly cleanup of individual code bits and code reuse for `clean::Attribute` handling.
The only change in behaviour should be that emitted sources are now being recorded and queried when trying to create src-links to local source-files.

This PR implements [RFC 1192](https://github.com/rust-lang/rfcs/blob/master/text/1192-inclusive-ranges.md), which is triple-dot syntax for inclusive range expressions. The new stuff is behind two feature gates (one for the syntax and one for the std::ops types). This replaces the deprecated functionality in std::iter. Along the way I simplified the desugaring for all ranges.
This is my first contribution to rust which changes more than one character outside of a test or comment, so please review carefully! Some of the individual commit messages have more of my notes. Also thanks for putting up with my dumb questions in #rust-internals.
- For implementing `std::ops::RangeInclusive`, I took @Stebalien's suggestion from https://github.com/rust-lang/rfcs/pull/1192#issuecomment-137864421. It seemed to me to make the implementation easier and increase type safety. If that stands, the RFC should be amended to avoid confusion.
- I also kind of like @glaebhoerl's [idea](https://github.com/rust-lang/rfcs/pull/1254#issuecomment-147815299), which is unified inclusive/exclusive range syntax something like `x>..=y`. We can experiment with this while everything is behind a feature gate.
- There are a couple of FIXMEs left (see the last commit). I didn't know what to do about `RangeArgument` and I haven't added `Index` impls yet. Those should be discussed/finished before merging.

This PR allows using methods from traits that are visible but are defined in an inaccessible module (fixes #18241). For example,
```rust
mod foo {
pub use foo::bar::Tr;
mod bar { // This module is inaccessible from `g`
pub trait Tr { fn f(&self) {} }
}
}
fn g<T: foo::Tr>(t: T) {
t.f(); // Currently, this is a privacy error even though `foo::Tr` is visible
}
```
After this PR, it will continue to be a privacy error to use a method from a trait that is not visible. This can happen when a public trait inherits from a private trait (in violation of the `public_in_private` lint) -- see @petrochenkov's example in #28504.

Now that https://github.com/jemalloc/jemalloc/commit/767d85061a6fb88ec977bbcd9b429a43aff391e6 is upstream, the relevant deadlocking issue which prompted our downgrade has been resolved. As a result, there's no known issue to *not* upgrade! This also re-enables jemalloc for the pc-windows-gnu target as known issues with that have also been fixed.
Closes #31030

This PR improves the import resolution algorithm.
First, it records that an import succeeded or failed for one namespace (by calling `decrement_outstanding_references_for` and `try_define_child` if successful) even if it is still indeterminate in the other namespace, fixing #31444.
Second, it starts importing bindings from globs as soon as the glob path is determined.
It maintains links from imported modules to their importers so that when a resolution becomes successful in an imported module, a corresponding binding will be added to the importer module.
It also maintains links from importer modules to imported modules so that we can determine if an undefined name is indeterminate or failing by recursively checking this in the imported modules.
This allows, for example:
```rust
mod foo {
pub mod baz {}
pub use bar::baz::*;
}
mod bar {
pub use foo::*;
}
```
It also allows cycles of pub glob imports, although by to the current shadowing rules, the only way for such a cycle to compile is if each participating module defines no names. Incidentally, this PR lays the groundwork for more permissive feature-gated shadowing rules.
Finally, this PR encapsulates almost all implementation details of import resolution in `resolve_imports` (some of which used to be in `lib.rs`) and refactors reexport recording, shadowed trait collecting, some duplicate checking, and the `private_in_public` lint out of the core import resolution algorithm and into a post-processing pass in `resolve_imports`.

Visit an overloaded += like a method call and not like an assignment.

To me it was unclear whether 'it' referred to the fold function, or the closure.

Right now there's just a smattering of `// ignore-foo` platforms which is ever
expanding as new ones are added. Instead switch to only running these tests on
Linux/OSX and then use a guaranteed-to-work but not-as-well-tested alternative
on other platforms.
