[PATCH] D17884: Disallow duplication of imported entities

[Amjad Aboud via llvm-commits]

aaboud updated this revision to Diff 49973.
aaboud added a comment.

Another try, this time I am uploading suggested solution by Don Hinton.
He is suggesting to make "imports" field in DICompileUnit of new type "unique vector".
Then we can get rid of AllImportedEntitys container and use directly the LLVMContext::impl::DIImportedEntitys instead
