How recent is your -CURRENT?  FYI, recently we fixed couple of
auto-vectorization bugs, i.e.,

http://svnweb.freebsd.org/base?view=revision&revision=249817
http://svnweb.freebsd.org/base?view=revision&revision=250593

I have feeling that one of these might fix your problem.

BTW, please note adding custom compiler/linker flags are not supported.
