The actual SourceLocation on an ASTNode is representing the whole ASTNode whereas in an LSP (for example) you are also interested in the SourceLocation of a name of a construct (e.g. variable decarlation, function definition, ...). This also properly encodes non-existend sources as `-1` in the JSON output (eliminating the use of `numeric_limits<size_t>::max()`).
