  [CIR] Add support for recursive record layouts (#140811)

While processing members of a record, we try to create new record types
as we encounter them, but if this would result in recursion (either
because the type points to itself or because it points to a type that
points back to the original type) we need to add it to a list for
deferred processing. Previously, we issued an error saying this wasn't
handled. This change adds the necessary handling.
