[PATCH] Emit comment for gc.relocate's showing base and derived pointers in human readable form

[Philip Reames]

The idea seems helpful and reasonable, but I am not familiar enough with this code to review.  I'd suggest checking git blame for the functions in question.

p.s. I suspect that this should be inside the annotation writer mechanism, but I haven't really checked to confirm.
