Reland "[ARM] __cxa_end_cleanup should be called instead of _UnwindResume."
This is relanding commit da1d1a08 . This patch additionally addresses failures found in buildbots & post review comments. ARM EHABI[1] specifies the __cxa_end_cleanup to be called after cleanup. It will call the UnwindResume. __cxa_begin_cleanup will be called from libcxxabi while __cxa_end_cleanup is never called. This will trigger a termination when a foreign exception is processed while UnwindResume is called because the global state will be wrong due to the missing __cxa_end_cleanup call.
