Creating minidump for uncaught exception on iOS.

Browse source 
This CL adds a minidump_generator that can write a minidump from a NSException
on iOS on an ARM cpu.

 This CL also install an uncaught exception handler on iOS, and use the
previous generator to write minidumps for any uncaught exception.
