Indeed, it shouldn't :| I think the main reason might not be SIMD, but
the additional hypothesis you put on the arrays (aliasing). This way,
todays compilers may not even need the actual SIMD instructions.
I have the same opinion as Francesc, it would only be useful for
operations that need more computations that load/store.
