[Bug #20989] Ripper: Pass compile_error 
For the universal parser, `rb_parser_reg_fragment_check` function is
shared between the parser and ripper.  However `parser_params` struct
is partially different, and `compile_error` function depends on that
part indirectly.

Revert "[Bug #20965] Define `it` like an ordinary argument (#12398)"

Reverts ruby/ruby#12398 as per https://bugs.ruby-lang.org/issues/20970#note-6 and https://bugs.ruby-lang.org/issues/20965#note-7.
We need more time to design the intended behavior, and it's too late for Ruby 3.4.

How about removing `%require “version”` since it is a definition to specify the minimum version of Bison and is not needed now that we have completely moved to Lrama?

94ad2c3fe9 Reduce creating rb_parser_string_t repeatedly for literals. 
Since #11698, `parser_str_new` makes `rb_parser_string_t` and `VALUE`
but discards the former, and then `STR_NEW3` makes the same thing
again.

Raise a compile error for break/next/redo inside eval in cases where it is optimized away

raise a SyntaxError even if inside a conditional block that is
optimized away.
