Delete AST.cpp, AST.h, ASTDump.cpp, ScopeRecord.h, and the dead get_builtin(MemberExpression const&) from Builtins.cpp. Extract ImportEntry and ExportEntry into a new ModuleEntry.h, since they are data types used by the module system, not AST node types. Inline ModuleRequest's sorting constructor and SourceRange::filename(). Remove the dead annex_b_function_declarations field from EvalDeclarationData, which was only populated by the C++ parser.
