Problem 3 is bogus as vector extensions are generic and use what ever exist for
your target.  Now the alignment should also be constraint by BIGGEST_ALIGNMENT
.

I am in the process of rewriting the vector extension documentation so it
should become more clear that it is a generic extension and has nothing to do
with the target at all except for the fact they become faster.
