Terminate pads, cleanup pads with `__clang_call_terminate` call, have
`catch` instruction in them because `__clang_call_terminate` takes an
exception pointer. But these terminate pads should be reached also in
case of foreign exception. So this pass attaches an additional
`catch_all` BB after every terminate pad BB, with a call to
`std::terminate`.
