For me the trunk with vectorization is certainly faster than 4.3, it is true
that 4.6 is slower.

4.3 -O3 -ffast-math 0m0.144s
4.3 -O3 -ffast-math -fno-tree-vectorize 0m0.167s
4.6 -O3 -ffast-math 0m0.194s
4.6 -O3 -ffast-math -fno-tree-vectorize 0m0.195s
4.6 -O3 -ffast-math -mavx 0m0.181s
trunk -O3 -ffast-math 0m0.127s
trunk -O3 -ffast-math -fno-tree-vectorize 0m0.176s
trunk -O3 -ffast-math -mavx 0m0.071s
