New compiler: Add AST nodes for function calls. Can compile hello world. (#240) Adds: - ast/Argument: AST node for an argument passed to a function. - ast/FunctionCall: AST node for a function call. - codegen/ModuleDeclarationRegistrar: The code generator registers module function declarations with this in order to determine module indexes and function indexes for instructions. - model/FunctionLink: this is a reference either: - from: a FunctionCall or a FunctionReference - to: a ModuleFunctionDeclaration or a UserFunction - optimizer/ReferencedFunctionGatherer: a visitor that determines which module functions and user functions are referenced, by looking at function calls and function references. Also: - CodeGenerator registers module functions - InstructionGenerator generates code for function calls - InstructionEmitter generates TOK_FUNC instructions - StoredTokenDecoder decodes TOK_FUNC instructions After all of this, the compiler can compile print("hello, world");
