Reland "[ARM] __cxa_end_cleanup should be called instead of _UnwindResume."

This is relanding commit da1d1a08694bbfe0ea7a23ea094612436e8a2dd0 .
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.
