           AOT snapshots can be obfuscated: that is all identifiers will be renamed    
           during compilation. This mode is enabled with --obfuscate flag. Mapping     
           between original and obfuscated names can be serialized as a JSON array     
           using --save-obfuscation-map=<filename> option. See dartbug.com/30524       
           for implementation details and limitations of the obfuscation pass.
