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.
