fixes #24305, refs #23807 Since #23014 `nkHiddenAddr` is produced to fast assign array elements in iterators. However the array access inside this `nkHiddenAddr` can get folded at compile time, generating invalid code. In #23807, compile time folding of regular `addr` expressions was changed to be prevented in `transf` but `nkHiddenAddr` was not updated alongside it. The method for preventing folding in `addr` in #23807 was also faulty, it should only trigger on the immediate child node of the address rather than all nodes nested inside it. This caused a regression as outlined in [this comment](#24322 (comment)). To fix both issues, `addr` and `nkHiddenAddr` now both shallowly prevent constant folding for their immediate children.
