Subject: Replace text annotations with explicit file/line for debug info
 (#967)

Rather than storing debug info as text annotations, store explicit file and line information. This will make it easier to experiment with outputting other serializations or representations (e.g. source maps), and will allow outputting debug info for binaries as well.
