This commit swaps the order of linking local native libraries and upstream
native libraries on the linker command line. Detail of bugs this can cause can
be found in #28595, and this change also invalidates the test case that was
added for #12446 which is now considered a bug because the downstream dependency
would need to declare that it depends on the native library somehow.
Closes#28595
We don't completely cover documentation tests in the testing chapter,
since we cover them in the documentation chapter. So make sure people
know that.
Fixes#28082
The original blog post referred to examples by their file names, and now
that it's in guide form, there is no file name. So edit the text so that
it makes a bit more sense.
Fixes#28428
The links in the rustdoc for several places in fmt were trying to link to
the std::fmt module but actually linking to std, which was confusing.
While trying to figure out why I noticed that the documentation chapter of
the Rust book has examples that show this same bug (although it doesn't seem
widespread in practice).

- Expand the first paragraph
- Improve readability by partitioning the chapter into the following
sections: "Patterns", "Type annotations", "Mutability", and
"Initializing bindings"
- Add "Scope and shadowing" section (fix#28177)

Travis CI has new infrastructure using the Google Compute Engine which has both
faster CPUs and more memory, and we've been encouraged to switch as it should
help our build times! The only downside currently, however, is that IPv6 is
disabled, causing a number of standard library tests to fail.
Consequently this commit tweaks our travis config in a few ways:
* ccache is disabled as it's not working on GCE just yet
* Docker is used to run tests inside which reportedly will get IPv6 working
* A system LLVM installation is used instead of building LLVM itself. This is
primarily done to reduce build times, but we want automation for this sort of
behavior anyway and we can extend this in the future with building from source
as well if needed.
* gcc-specific logic is removed as the docker image for Ubuntu gives us a
recent-enough gcc by default.

This prevents ICEs when old crates are used with a new version of
rustc. Currently, the linking of crates compiled with different
versions of rustc is completely unsupported.

Some minor parts of AST and HIR were not visited by the `visit::walk_xxx` methods - some identifiers, lifetimes, loop labels, attributes of exported macros - but nothing as serious as in, for example, https://github.com/rust-lang/rust/pull/28364.
\+ Added a convenience macro for visiting lists (including Options)
\+ Removed some pre-Deref-coersions `&**` noise from visitors

I just removed the num_cpus dependency (because we don't want that in there), using 4 threads instead.
I should add that Veedrac asked me to submit this here in his name.
