merge revision(s) 3d19409637de1462b6790d2a92344bf0a10d8c52: [Backport #20090]

	Use index for referring to symbols in `args` rule instead of named
	 references

	In `args: args ',' arg_splat`, `args` is not unique name.
	Currently the associated rule is interpreted as
	`$$ = rest_arg_append(p, $$, $3, &@$);`.
	The action works as expected because `$$` is initialized with
	`$1` before each action is executed.
	However it's misleading then change to use index.
