register destructor functions annotated with __attribute__((destructor)) using __cxa_atexit or atexit. Register destructor functions annotated with __attribute__((destructor)) calling __cxa_atexit in a synthesized constructor function instead of emitting references to the functions in a special section. The primary reason for adding this option is that we are planning to deprecate the __mod_term_funcs section on Darwin in the future. This feature is enabled by default only on Darwin. Users who do not want this can use command line option 'fno_register_global_dtors_with_atexit' to disable it. rdar://problem/33887655 Differential Revision: https://reviews.llvm.org/D45578 llvm-svn: 330199
