[modules] Fix bug where an anonymous namespace could cause the containing namespace to not merge properly. We have an invariant here: after a declaration reads its canonical declaration, it can assume the canonical declaration is fully merged. This invariant can be violated if deserializing some declaration triggers the deserialization of a later declaration, because that later declaration can in turn deserialize a redeclaration of that first declaration before it is fully merged. The anonymous namespace for a namespace gets stored with the first declaration of that namespace, which may be before its parent namespace, so defer loading it until after we've finished merging the surrounding namespace. llvm-svn: 232455
