If you include the location range for everything in the json output, it's much
easier to implement navigate-to-declaration in an IDE. For example, if there is
code:

logger.trace(...);

json only outputs "line": 18.
But if it instead put: "range": { "start": {"line": 18, "col": 4}, "end":
{"line": 18, "col": 16}}

Then it's easier for an IDE to find the identifier under the cursor.

Similarly, IDEs often allow you to "fold" code -- collapse a declaration so you
don't have to see it, or collapse a function body or a block. Including a range
means the IDE doesn't need to parse D.
