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.
