It looks like this problem is solved in the current 4.7 and 4.8 branches. At
least on an avx machine, the best performance found by the code in comment #4
jumps from 5.3Gflops in 4.6 to 13.9Glfops in 4.7/4.8. Great work.

I can't test this right now on interlagos, but I guess this could be OK as
well.
