Turned out that column numbers in diagnostics used to be off by one, starting at 0 instead of 1.
Also took the opportunity to implement a line cache aiding in determining the line number for a given source position using a little binary search instead of walking the source. Saves a second or so on the non-parallel test suite (~1.8%).
In turn I also removed the
Range#lineandRange#columnproperties in preparation of making the AST more easily serializable eventually.
