First cut at adding arm64 Linux / Android support to Breakpad.

Browse source 
This is an initial attempt to add Arm64 (aarch64) support to Breakpad for
Linux / Android platforms.  This CL adds the Arm64 data structures, but does
not yet implement the Android getcontext support or CPUFillFromThreadInfo /
CPUFillFromUContext.
