Nit: Can we rename this to ParseModuleItemList, for more consistency with the
above? ParseModule sounds like it should either return a single AST node
corresponding to a Module, or be an entry point for parsing module scripts.

Sounds good, will rename in a one of these followups.

   Statement* ParseModuleItem(bool* ok);
   Literal* ParseModuleSpecifier(bool* ok);
   Statement* ParseImportDeclaration(bool* ok);
