Code review for 6190d828cd2

* Fix the comment of init_dummy_sjinfo() to remove references to
  non-existing parameters 'rel1' and 'rel2'.

* Adjust consider_new_or_clause() to call init_dummy_sjinfo() to make
  up a SpecialJoinInfo for inner joins like other code sites that
  were adjusted in 6190d828cd2 to do so.
