When I was doing the infrastructure work to remove the knowledge that arguments
used TREE_LIST's in the backends, I noticed the overloaded machine specific
intrinsic support for C/C++ was another place to be changed.  I was just about
to start hacking on the front ends to get them to use a common infrastructure
for arguments and use vector support.  You might glance over to my patches to
see if the infrastructure support in tree.h is sufficient to your needs:
