[PATCH] D50495: [DebugInfo] Do not generate duplicated label debug info if it has been processed.

[Hsiangkai Wang via Phabricator via llvm-commits]

HsiangKai added a comment.

Is there anything I should address?

Without this patch, it will generate two DW_TAG_label for the same label if retainedNodes also contains the label.
This patch will record processed labels in 'Processed' DenseSet to avoid generating duplicated DW_TAG_label for them.
