vaarg accesses memory too.

Note also that the back end code generators can generate other memory 
accesses and those won't be visible at the LLVM level.  These include 
spill code, argument passing through the stack, any code generated 
internally for intrinsics or for exceptions on unwind, and of course 
any native run-time libraries like malloc/free.
