The Compiler should be able to vectorize the expression template expanders
(it isn't due to missing inlining and aliasing optimizations). Manually
providing SIMD support would be a tedious task - you'd need to specialize
f.i. KernelEvaluator<InlineKernelTag>::evaluate() for different
operations(!), dimensionality and of course types.
Best leave it to compiler improvements. I'll hope gcc 4.1 with
patches will get there, no hope for Intel.
