This fixes issues with subrules in the Menhir backend by: 1. Adding a syntaxdefn field to pp_menhir_opts in types.ml 2. Modifying suppress_rule to check if a nonterminal is non-maximal in the subrule hierarchy in lex_menhir_pp.ml 3. Adding a skip_subrule_validation parameter to check_and_disambiguate in grammar_typecheck.ml 4. Passing the appropriate flag when generating Menhir output in main.ml The Menhir backend should 'only take the maximal elements from the subrule order' as documented in the comments. This implementation correctly suppresses non-maximal elements to ensure the generated parser works properly with subrules.
