LGTM, thanks!

So the actual problem is that the ASTImporter will only copy over the definition to the destination decl if the source decl `isCompleteDefinition`. So then when we tried to add the typedef decl to the `CXXRecordDecl` that the ASTImporter created for `A`, it would try to query its definition which didn't get copied over, and hence we assert.
