Support symbol dumping for ARMV8 iOS apps.

Support symbol dumping for ARMV8 iOS apps.

In my testing, ARM V8 object files and ARM V8 slices of universal binaries do
not contain debug_frame sections (at least at this time), and hence dump_syms
does not output CFI for ARM V8 even in the absence of the "-c" flag.

Hi,

I don't see any obvious place for adding unit tests but would be happy to do so
if I'm missing something.

Thanks,

Colin

As discussed offline, please review the name of the architecture and the defines
using the new lipo available on the latest XCode version.

 You should also be able to find the right name for the defines using the .h
file available in it too.

Closing this patch and proceeding with https://breakpad.appspot.com/642002/
instead, as that patch is in a checkout based at trunk rather than trunk/src.
