Yes, that was what i was planning to do, but if you are going to do it, 
i'll leave it to you because i have about 2000 other things to do.

It should stash the info somewhere, possibly 
SSA_NAME_PTR_INFO->max_allocated_size 
(i know it can compute min, etc, but for estimating iteration counts, we 
have to use MAX).

Right, just as soon as you look up what bits you need to pass it from 
the builtin_object_size docs :)

(Yes yes, i know, easily solvable :P)
