AIX/s390: [torque] check TNode return types of CSA macros

Port 20d29a36

Original Commit Message:

    This disallows using CSA macros from Torque that have a Node* return
    type instead of TNode<>. By enforcing CSA types at the boundary between
    CSA and Torque, we can ensure that the Torque types and the CSA types
    match.

    As a drive-by, this CL adds a bit more of CSA typing where it made sense.
