OpenMP auto-simd

Basically, any implementation for which a (significant) directive becomes a no-op is either a) not implementing the feature as intended, or b) is implementing it for a device configured differently to the one that inspired the directive. Since I'm pretty sure that (b) is not the case I settled my opinion on (a).

Now, it may be that the original intention is flawed and the deviant implementation is superior, but that's another matter.
