This PR adds support for aarch64 on both Linux and macOS targets. It's basically identical to x86_64, just with a different set of callee-saved registers and simpler stack alignment in the aarch64 ABI. I suspect some of the alignments can be relaxed on ARM but I didn't want to dive too deeply into that so they are left the same as x86.
Travis supports ARM CI runners for Linux so I added those. There's no ARM macOS support on Travis (yet?), but I've tested locally on an ARM Mac.
