ext/ripper: Introduce a simple DSL for ripper.y code generation
Currently, parse.y actions are hard to read and write because the code
has double meaning (for core parser and for ripper). I think that, if
it is easy to write ripper's code shortly and simply, the double meaning
trick is not needed.
For the sake, this change adds a simple DSL for ripper's code. For
example, in parse.y, we can write:
/*% ripper: stmts_add(stmts_new, void_stmt) %*/
instead of:
$$ = dispatch2(stmts_add, dispatch0(stmts_new),
dispatch0(void_stmt));
