In principle it is applicable, but the same file also has other changes
in head which were not MFCd, so just MFCing this one commit does not
make much sense.  For example, the earlier cast fixes were part of a
much larger commit by Pedro Giffuni, adding "experimental support for
amdfam10/barcelona CPUs":

http://svnweb.freebsd.org/base?view=revision&revision=251212

Does it still make sense to backport such experimental changes to an old
stable branch?  Of course I could split off just the changes to
emmintrin.h, and leave the others out, but then we would have a partial
MFC.  I'm not sure if that is the usual way of doing things...
