Hagane SIMD vector library

This is a crate that provides an SIMD vector library for Rust and specifically the ObjC bridge hagane, it's nowhere near as polished or complete as the language support in Clang / OpenCL but it's intended to be a start to get us out and be productive at least.

The main goal is to be ABI compatible with the Apple standard library simd for use on macOS and iOS. Right now it only builds on Apple platforms since we depend on libSystem, but the goal is to replace those bits as soon as possible.

Build the source

Right now you can regenerate the source code from the Ruby script via rake, this is a temporary measure until the point I am happy with the output and try to write optimisations. Then we'll fossilise the code and remove the generator.
