Summary:
It used to be string which:
1. Doesn't have enough information for parametric models
2. Doesn't have good type
Changing this blows up in clang frontend, but I think it's for the better

Summary: procnames will depend on Typ.t soon and we need to go from `type_ptr` to `Typ.t` when creating procnames. `CType_decl` does this translation it can't depend on `mk_procname_` functions.
