Gee, we're just upportting a change from 3.3 to handle more than 8(?) 
vector arguments in non-stdarg functions, and where they spill into 
memory so that it conforms to the moto altivec ABI.  We changed it to 
use two passes.  Are others interested in actually following the moto 
ABI or are we alone in this regard?
