Why an object vs something like:
```
struct RecordInits {
SmallVector<std::pair<const CXXBaseSpecifier *, Expr *>> BaseInits;
SmallVector<std::pair<const FieldDecl *, Expr *>> FieldInits;
};
RecordInits RecordInitListHelper(const InitListExpr *InitList);
```
Is it because of the optional storage needed for the union?
