The first loop now gets vectorized, it didn't because of:

/* Currently not vectorized because we get too many BBs in the inner-loop,
   because the compiler doesn't realize that the inner-loop executes at
   least once (cause k4), and so there's no need to create a guard code
   to skip the inner-loop in case it doesn't execute.  */


So, the correct fix is to expect 2 outer loop vectorized on targets that
support realignment.

I'll fix the test.

Ira
