Similar to what we have done downstream, some time ago:
https://svnweb.freebsd.org/changeset/base/353936
This followed some discussions on the freebsd-arch mailing lists, and
most people agreed that it was a better default, and also it worked
around several issues where clang generated libcalls to 64 bit atomic
primitives, instead of using cmpxchg8b.
