Optimise reductions and dotprod with more vectorisation
Turns out that if you don't supply -ffast-math, the C compiler will
faithfully reproduce your linear reduction order, which is rather
disastrous for parallelisation with vector units.
This changes the summation order, so numerical results might differ
slightly. To wit: the test suite needed adjustment.
