Log:
  Pull in r336008 from upstream clang trunk:
  
    Request init/fini array on FreeBSD 12 and later
  
    Summary:
  
    It seems a bad idea to change the default in the middle of a release
    branch due to possible changes in global ctor / dtor ordering between
    .ctors and .init_array. With FreeBSD 11.0's release imminent lets
    change the default now for FreeBSD 12 (the current development
    stream) and later.
  
    FreeBSD rtld has supported .init_array / .fini_array for many years.
    As of Jan 1 2017 all supported FreeBSD releases and branches will
    have support.
