Summary: Introduces a separate target for comment manipulation. Currently, comment manipulation is in BreakableComment.cpp. Towards implementing comment reflowing, we want to factor out the comment-related functionality, so it can be reused. Start simple by just moving out getLineCommentIndentPrefix. Patch by Krasimir Georgiev!
