Vyacheslav Egorov 7d5231796e [VM, Precompiler] Support obfuscation of the symbolic information in precompiler ...

Obfuscation is controlled by obfuscate flag in Dart_IsolateFlags.

Obfuscation of identifiers is performed during script tokenization - when TokenStream is generated from the source. All kIDENT and kINTERPOL_VAR tokens are renamed consistently using a persistent obfuscation map stored in ObjectStore::obfuscation_map.

Some identifiers (pseudo-keywords, arithmetic operators, builtin recognized methods and entry-points) are not renamed to keep name based lookups from breaking. All other identifiers are renamed.

Constant instances of Symbol-s (both created via literal syntax #ident and using constant constructor const Symbol("ident")) are renamed consistently with corresponding identifiers.

Script urls and Library urls and names are also obfuscated.

Obfuscation map can be dumped as a JSON array at the end of precompilation using Dart_GetObfuscationMap API.
