a7bd12d2 - Serialization: Exclude types from the same module as dependencies of an enum.

Serialization: Exclude types from the same module as dependencies of an enum. There can be a circularity when two enums recur through each other, and deserialization currently is not set up to robustly detect and avoid these circularities. This should avoid regressions, but re-exposes some possible cases that should require recovery in mix-and-match situations. Short-term fix for rdar://problem/32337278.
