This will result in some extra wasted space on all objects that do not contain 
vectors.  I've now fixed (somewhat over defensively, but I'll relax it a bit 
before the next release) the ivar layout code in the runtime so that it will 
ensure that the instance variables all have the alignment that they need (or, 
currently, a bit more in some cases).  In GC mode, this extra padding is not 
added.
