It sounds like a good idea to allow targets to enable it.  I published https://reviews.llvm.org/D44735 to do it.

The advantage of the approach in this patch is that it gives a guarantee of the minimum VF.  I'm not sure if the TTI callback for maximizing bandwidth will ensure that, since it still considers all powers of 2 between 1 and the MaxVF.
