[Bug target/25500] REGREGRESSION: SSE2 vectorized code is many times slower on 4.x.x than on 3.4.4

Oh, I looked a little more and yes it depends on the arch you are building for
but only for 4.x.

Since you are using SSE, you should add also -march=i686 or -march=k8 so that
the code is also tuned for the processor you are using.  

Anyways the problem with i386 with 4.0 is really just PR 14295.
