Ick.  So line number information is only available at debug stop points?
That's bad when compiling optimized code since the debug stops kill
optimization, don't they?

We have our own privately-maintained way of tracking line information even
in optimized code but it's a big hack and not something suitable for
pushing upstream.

I thought I saw something on the list recently about someone working on
integrating line number information directly into LLVM Instructions, SDNodes,
MachineInstructions, etc.  Am I mis-remembering?  If not, what's the status
of that?  We'd like to switch over to a proper scheme if we can.
