file" error when making a query from an unsaved editor buffer at an
offset greater than the length of the file on disk.

The parser does intra-file resolution. It's only a best-effort but
it's extremely fast, so we try it first and fall back to the loader-based
implementation if it fails.
Also:
- factor definitionResult so it doesn't depend on either go/types.Object
or go/ast.Object.
- guessImportPath: make importPath=="" result an error,
since you can't import the empty string. Simplify importQueryPackage.
- Make fastQueryPos continue in face of minor parse errors.
- describe: eliminate old TODO; suppress log statement.
