`fieldDecl` document says that fieldDecl is "an instance of this class is created by Sema::ActOnField to
represent a member of a struct/union/class.". So for static class members, they should not belong to `fieldDecl` as they are not bound to class instances.
 
Technically, we can't apply `hasStaticStorageDuration()` and `isStaticStorageClass` over a `fieldDecl`.
