* Add a new `SExpDouble` atom and change `SExpNumber` to `SExpInteger`. * Allow for negative integers in deserialization. * Add support for `LocalVariable`s and related instructions. * Function objects are now represented by actual S-expressions generated with the new `FunctionToSExp` method. Previously, they were only represented by a symbol containing their canonical name. * The top-level tag for a serialized flow graph is now `FlowGraph`, not `function`. This avoids confusion between serialized flow graphs and serialized function references. Similarly, the old `FunctionToSExp` method is now called `FlowGraphToSExp`. * Made all SExpression* returning functions that take Object (or subclass) instances return nullptr if the passed in instance is the null object, except for ObjectToSExp, which returns the symbol `null`. * Factored out creating tags for the different kind of block/function entry and also created an `Entries` section to the top-level `FlowGraph` form that contains function entry points similar to the `Constants` one instead of inlining entries as separate elements in the `FlowGraph` form. * Additional extra information in verbose mode for some elements.
