AST Serialize Reading (#1409)

* Try to fix problem with C++ extractor concating tokens producing an erroneous result.

* Improve naming/comments around C++ extractor fix.

* Another small improvement around space concating when outputing token list.

* Handle some more special cases for consecutive tokens for C++ extractor concat of tokens.

* WIP AST serialization.

* Comment out so compile works.

* More work on AST serialization.

* WIP AST serialize.

* WIP AST Serialization - handling more types.

* WIP: Compiles but not all types are converted, as not all List element types are handled.

* Compiles with array types.

* Finish off AST serialization of remaining types.

* Remove ComputedLayoutModifier and TupleVarModifier.

* Add fields to ASTSerialClass type.

* Construct AST type layout.

* AST Serialization working for writing to ASTSerialWriter.

* Removed call to ASTSerialization::selfTest in session creation.

* Fixes for gcc.

* Diagnostics handling - better handling of dashify.

* Improve comment around DiagnosticLookup.

* Updated VS project.

* Write out as a Stream, taking into account alignment.

* First pass at serializing in AST.

* Added support for deserializing arrays.

* Small bug fixes.

* Fix problem calculating layout.
Split out loading on entries.

* Fix typo in AST conversion.
