[PATCH] D45045: [DebugInfo] Generate debug information for labels.

Hi,

I'm generating these labels from the Rust compiler, which is far from a minimal example.

I'm actually conflicted about what should happen if code containing a label is removed, but the label is marked to be "retained". Maybe it does make sense for those to stay with some kind of a special offset or flag to indicate so. What do you think?

FWIW, my working assumption is that the `-unreachableblockelim` pass is removing code that contains labels, resulting in 0x0 offsets.

I'll try to get a simple example that gives a label with an 0x0 offset.
