Spans
The offsets part of a full position, consisting of 2 or 3 entries:
- start: the start offset of the span, in characters from start of file
- end : the end offset of the span
- point: if given, the offset where a single
^would be logically placed
Spans are encoded according to the following format in little endian: Start: unsigned 26 Bits (works for source files up to 64M) End: unsigned 26 Bits Point: unsigned 12 Bits relative to start NoSpan encoded as -1L (this is a normally invalid span because point would lie beyond end).

A span indicates a range between a start offset and an end offset. Spans can be synthetic or source-derived. A source-derived span has in addition a point. The point lies somewhere between start and end. The point is roughly where the ^ would go if an error was diagnosed at that position. All quantities are encoded opaquely in a Long.
