This python script will consume an appropriately formatted JSON file and
output either a Rust file for use in librustc_platform_intrinsics, or an
extern block for importing the intrinsics in an external library.
The --help flag has details.
This adds support for flattened intrinsics, which are called in Rust
with tuples but in LLVM without them (e.g. `foo((a, b))` becomes `foo(a,
b)`). Unflattened ones could be supported, but are not yet.
This is necessary to reflect the ARM APIs accurately, since some
functions explicitly take an unsigned parameter and a signed one, of the
same integer shape, so the no-duplicates check will fail unless we
distinguish.
It is very difficult to find tidy problems in the midst of the output of
the LLVM/jemalloc/etc. build, and travis is great for the former, so
lets remove that problem.

Encountered an issue with `pacman` while going through the guide for installing the `mingw` toolchain on Windows with `msys2`, after some googling I found the [solution](https://github.com/Alexpux/MSYS2-packages/issues/163#issuecomment-73555971).
I thought it would be good to update the README so people don't get frustrated. 😃

After submitting #28031, I ran a [script](https://gist.github.com/durka/a5243440697c780f669b) on the rest of src/ and found some anomalies. In this PR are the fixes that I thought were obvious (but I might be wrong!). The others I've submitted in issue #28037.
If you have an `Iterator<Item=String>` (say because those items were generated using `.to_string()` or similarly), borrow semantics do not permit you map that to an `Iterator<&'a str>`. These two implementations close a small gap in the `String` API.
At the same time I've also made the names of the parameters to `String`'s `Extend` and `FromIterator` implementations consistent.
We were using them for every expansion, instead of using `Name`.
Also converted `CompilerExpansion` into an enum so its nicer to use and takes up less space.
Will profile later, but this should be a small improvement in memory usage.

As of now, when you open a page in the Rust book and other books made with `rustbook`, you cannot scroll with your keyboard, whether using spacebar or arrow keys, unless you explicitly focus on the content div by clicking.
This PR fixes the issue by removing the bound on the content div size and by sticking the TOC with `position: fixed` rather than restricting the content to the window height.

This PR rewrites the code that previously relied on `PATH_MAX`.
On my tests, even though the user gives the buffer length explicitly, both Linux's glibc and OS X's libc seems to obey the hard limit of `PATH_MAX` internally. So, to truly remove the limitation of `PATH_MAX`, the related system calls should be rewritten from scratch in Rust, which this PR does not try to do.
However, eliminating the need of `PATH_MAX` is still a good idea for various reasons, such as: (1) they might change the implementation in the future, and (2) some platforms don't have a hard-coded `PATH_MAX`, such as GNU Hurd.
More details are in the commit messages.
Fixes#27454.
