pass_tree_profile seems to be more appropriate place for this transformation. You already have some infrastructure in place there (see value-prof.c), so it might be easier to implement than starting from scratch. In that case, you do not even have to worry about the internal representation too much, just add what you need to tree_values_to_profile (and use get_call_expr_in to find function calls in statements).
