[LLVMdev] using -debug-ir to map identify IR mapping

[Muneeb Khan]

Yes, I am using opt and llc from the same version (3.5).
I know that there were issues with debug-ir in 3.4. I have explored the source tree myself for 3.5 and I know that the pass -debug-ir does kick in with opt.
But I have no clue of what happens with the debug information in (and after) the llc pass.
