Devang Patel fa31d38aad Introduce DebugInfoProbe. This is used to monitor how llvm optimizer is treating debugging information. 
It generates output that lools like

8 times line number info lost by Scalar Replacement of Aggregates (SSAUp) 
1 times line number info lost by Simplify well-known library calls 
12 times variable info lost by Jump Threading
