Hello.
Quite a few of the links in the `core` module concerning redirection to additional primitive type documentation are broken. I noticed in #30214 that there seemed to be a consensus with linking across to `std` module documentation from the `core` module. This is what I've done with the `core` modules for primitive types.
If the changes here are good to go forward with, I'll happily tend to adding more documentation links for the extension traits in the aforementioned issue if need be.

Use unordered nested list for stabilised APIs to improve readability. This makes the release notes for 1.7 a bit longer, but I don't think we should optimise for brevity here. It's a bit inconsistent since the other releases are not done this way, so feel free to ignore this change.
Also:
- Add link to `u32::checked_neg`
- Remove trailing back tick from BTreeMap line

The default implementations (with `where Self: Sized`) are so that methods that take `self` by value can exist in a trait that’s implemented for dynamically-sized types (`str` and `[u8]`).

This commit implements documentation generation of the nomicon, the book, the
style guide, and the standalone docs. New steps were added for each one as well
as appropriate makefile targets for each one as well.
These commits add support to the rustbuild build system to compile non-build-system compilers. For example this will allow creating an ARM compiler on a x86 system. The high level way this works is:
* The only compiler ever run is the build target compiler. No other compiler is assumed to be runnable.
* As a result, all output artifacts come from the build compiler.
* The libs for the stageN cross-compiled compiler will be linked into place after the build target builds them.
This will break the assumption that a compiler never links to anything it didn't itself produce, but it retains the assumption that a compiler only ever links to anything built in the same stage. I believe this means that the stage1 cross-compiled compilers will still be usable.
I tested this by creating an `arm-unknown-linux-gnueabihf` compiler. So far the linking ended up all working OK (including LLVM being cross compiled), but I haven't been able to run it yet (in QEMU for a raspberry pi). I think that's because my system linker is messed up or something like that (some newer option is assumed when it's not actually there).
Overall, though, this means that rustbuild can compile an arm-unknown-linux-gnueabihf compiler. Ideally we could even start shipping nightlies based on this at some point!

the libs and the lang suteams. The full list of changes are:

This applies the same fix as added in 595d5b2f which is to just compile all
valgrind tests statically instead of dynamically. It looks like this is a
resurgence of either #30383 or #31328 in some weird fashion.
I'm not actually sure what's going on with the bots, and it's unclear whether
this is a valgrind bug or a libstd bug, but for now let's just get things
landing again.
Closes#30383

When cross compiling for a new host, we can't actually run the host compiler to
generate its own libs. In theory, however, all stage2 compilers (for any host)
will produce the same libraries, so we just require the build compiler to
produce the necessary host libraries and then we link those into place.
This switches the defaults to ensure that everything is built with the build
compiler rather than the host compiler itself (which we're not guaranteed to be
able to run)
Currently all multi-host builds assume the the build platform can run the
`llvm-config` binary generated for each host platform we're creating a compiler
for. Unfortunately this assumption isn't always true when cross compiling, so we
need to handle this case.
This commit alters the build script of `rustc_llvm` to understand when it's
running an `llvm-config` which is different than the platform we're targeting for.
This commit fixes a longstanding issue with the makefiles where all host
platforms bootstrap themselves. This commit alters the build logic for the
bootstrap to instead only bootstrap the build triple, and all other compilers
are compiled from that one compiler.
The benefit of this change is that we can cross-compile compilers which cannot
run on the build platform. For example our builders could start creating
`arm-unknown-linux-gnueabihf` compilers.
This reduces the amount of bootstrapping we do, reducing the amount of test
coverage, but overall it should largely just end in faster build times for
multi-host compiles as well as enabling a feature which can't be done today.

Refinement of paragraph referenced by [this issue](https://github.com/rust-lang/rust/issues/31927).
The paragraph in question had been adjusted already, but I've made some further clarifications which should help with readability and not leave the reader any `dangling pointers`.
