Hi Anton,

I have no opinion or background to decide if this implements the feature properly, but the patch itself looks great to me.

One minor change though: please remove __builtin_altivec_abs_v4sf.  Instead of having the builtin, you can just implement vec_abs with the corresponding expanded code in the header.  Feel free to apply the patch (or resend and I'll apply) with that change.
