This looks like it was fixed on the trunk, we no longer have any movss/movl.

The movss instructions were eliminated on trunk by Vladimir Makarov's "patch to
solve recent SPEC2000 degradation" in r178019:
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01954.html
http://gcc.gnu.org/ml/gcc-cvs/2011-08/msg01034.html
The code generation change at that point is:
