[PATCH] D17884: Disallow duplication of imported entities

[don hinton via llvm-commits]

hintonda added a comment.

Could you use a SetVector or SmallSetVector instead of a DenseSet for DIImportedEntities?  It's equivalent to what you've proposed, but since it knows when it inserts a new one, maintaining the vector is much cheaper.
