[LLVMdev] ARM unwinding bug

My initial focus certainly isn't Android, it's probably the biggest
application of an ARM port sure, but currently plain ARMv7 Linux is what
I'm targeting. Windows uses it's own unwinder from the OS and so libunwind
is cross-plat specific thing. Perhaps it'd be worth trying to get it
implemented, I did look and it looked not too difficult, but that was me
glancing over the code in a few minutes.

4.8.4, again packaged from Ubuntu 14.04 LTS, not sure if they include any
patches that'd change this behaviour.

Ben.
