- Add new getSourceReport kind 'Profile'. - Add "profileTicks" to source ranges that have profile data. - "profileTicks" is organized as three arrays: positions, inclusive ticks, and exclusive ticks. These arrays are indexed together. - Keep source positions in profile sorted by token position value. - Misc improvements to debug printing in profiler. - Add unit test for profile getSourceReport.
