Due to this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040712/016089.html

We store function pointers in the C++ vtables instead of function descriptors. 
This is a bug, but I don't intend to be the one to fix it. :)

If someone is interested, they will need to figure out how to represent the
needed IA64-isms in LLVM, then implement FDESC_EXPR in the C front-end.

IA64 has numerous issues.  Until the backend is more complete, we don't need to
track details like this.
