Sounds good to me.

One issue I do have is with:

   (The second suggestion was to use vector modes only if they are really
   supported by the target, and use a similarly-sized vector type
   otherwise; this is quite complex, probably more than these two items I 
   implemented).

If you only define vector modes for supported targets, how will a
SIMD-less target use generic vectors?
