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");

Add scope handling for functions and variables (#690) * Add Report.debug * Implement function call scoping * Implement variable scoping - Rename `Identifier::scope` to `calling_scope`, and concatenate the identifier scope into `name` if necessary. - Track current scope in SemanticAnalyzer, similar to UserFunctionVisitor. - Use current scope in SemanticAnalyzer when visiting identifiers. * Update grammar for `::identifier` global scoping * Introduce ScopableName for function resolution * Address review comments - Check for display_debugs missing * Add ScopableName for identifier resolution * Some cleanup - Remove `Identifier::calling_scope`, as it is tracked in the semantic analyzer - Refactor `ScopeName::exists` to `global` for better clarification of its use - Removed `X::maybe_scoped_string/name` * Address self-review comments * Rename `Function::module_name` to `scope`

Add limited support for user functions (#262) Adds: - ast/UserFunction AST node for user-defined functions. - astbuilder/AvailableUserFunction: reference to a parse tree for a user function. - The AST builder only generates ASTs for user functions that are actually referenced. - astbuilder/UserFunctionVisitor: visits (builds an AST for) a parse tree for a user function. - This happens after the .src or .inc file has been otherwise processed, so this class serves to hook up the correct SourceFileIdentifier to the AST.
