Disallow mask reduction vectorization
When you trick bool pattern recognition to use a mask type for a
reduction PHI you'll figure we're not ready to handle this because
epilogue creation isn't expecting this yet. The following reverts
part of the last change and makes this explicit.
* tree-vect-loop.cc (vectorizable_reduction): Do not allow
mask reductions.
```
