[PATCH] D56651: [ASTImporter] Fix importing OperatorDelete from CXXConstructorDecl

[Raphael Isemann via Phabricator via cfe-commits]

teemperor updated this revision to Diff 182718.
teemperor added a comment.

- Moved code into the VisitFunctionDecl function.

I don't mind if we clean up that function in a later commit. Thanks for the 
feedback!
