We previously moved container identification later in CodeGen in order to preserve information for AlignmentCalc. However, Flattener needs to know if a class is a container in order to apply its special handling for this case. This new approach moves container identification in front of Flattener, but has Container own a type node, representing its layout. This underlying type node can be used for calculating a container's alignment in a later pass.
