Initial patchset to get the testsuite running against armv7 and arm64 iOS devices.

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.
