Normal customer devices won't be able to run these devices, we're hoping to get a public facing bot set up at some point. There will be some smaller follow-on patches. The changes to tools/lldb-server are verbose and I'm not thrilled with having to skip all of these tests manually. There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64" means it's an ios device, and I need to review & clean these up with an OS check as well. (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't cause problems, but it's not an assumption I want to rely on). I'll be watching the bots for the rest of today; if any problems are introduced by this patch I'll revert it - if anyone sees a problem with their bot that I don't see, please do the same. I know it's a rather large patch. One change I had to make specifically for iOS devices was that debugserver can't create files. There were several tests that launch the inferior process redirecting its output to a file, then they retrieve the file. They were not trying to test file redirection in these tests, so I rewrote those to write their output to a file directly. llvm-svn: 313932
