Here is an updated patch, which now does no optimization in the
big-endian case. Given the current status of big-endian + neon
support, I guess it is not a serious problem.

I have also added runtime tests.

I will later post an additional patch (on top of this one), which
enhances the tests so that they can be run in big-endian mode too.
