da37301f08 Keep room in the token buffer for the terminator 
tokspace stops doubling as soon as the buffer reaches the token's length,
so a copy that lands exactly on the end leaves tokfix writing its
terminator one byte past it.  No caller passes a large enough n to reach
that today, but the invariant tokfix relies on is worth holding.

This reverts commit 2239d54348d9f1f7768860efc9e76876f85766d8.

056997cbcd Remove needless ruby2_keywords field from struct rb_args_info 
`ruby2_keywords` is set only to be `0` in parse.y.
However `args->ruby2_keywords` is initialized with `0` by `MEMZERO`
in `rb_node_args_new` function and `body->param.flags.ruby2_keywords`
is initialized with `0` by `ZALLOC` in `rb_iseq_constant_body_alloc` function,
so `args->ruby2_keywords` does nothing for `body->param.flags.ruby2_keywords`.

e96bbd718e Remove needless parse.y new_nil macro 
In the past parse.y and ripper had different `new_nil` definition
so that `new_nil` returns `nil` for ripper.

```c
// parse.y
#define new_nil(loc) NEW_NIL(loc)

// ripper
#define new_nil(loc) Qnil
```

However Rearchitect Ripper (89cfc1520717257073012ec07105c551e4b8af7c)
removed `new_nil` definition for ripper then this commit removes
needless parse.y macro and uses `NEW_NIL` directly.

// ripper
#define value_expr(node) ((void)(node))

5179b7fb3f Rename mlhs rule to mlhs_items for clarity in parse.y 
Since `mlhs` is already defined as a nonterminal as follows, using the same name as a parameterizing rule is a bit confusing, so rename the parameterizing rule.

2ccb2de677 Make RubyVM::AST.of return a parent node of NODE_SCOPE 
This change makes `RubyVM::AST.of` and `.node_id_for_backtrace_location`
return a parent node of NODE_SCOPE (such as NODE_DEFN) instead of the
NODE_SCOPE node itself.
(In future, we may remove NODE_SCOPE, which is a bit hacky AST node.)

This is preparation for [Feature #21543].
