Convert vec<> into a POD.

This fixes PR 55398 by making vec<> a true POD.  I thought we could get
away with having private fields, but we can't.  We fail to pass vec<>
instances through varargs.

The patch makes every field public and mangles the field names in the
hope that no future patch will try to make use of them directly.  It's
horrible, but I could not think of anything better.
