        * include/line-map.h (source_location): In the table in the
        descriptive comment, show UNKNOWN_LOCATION, BUILTINS_LOCATION,
        LINE_MAP_MAX_LOCATION_WITH_COLS, LINE_MAP_MAX_SOURCE_LOCATION.
        Add notes about ad-hoc values.
If this is documenting current state, then it's OK to go in now.  If 
it's documenting future state, then it can go in with the rest of the 
patches.
