Fix for BUG#8711: "<=>" may have true value for NULL arguments, so make
Item_func_equal::not_null_tables() always return 0.
mysql-test/r/join_outer.result:
Testcase for BUG#8711

Fix for BUG#8711: "<=>" may have true value for NULL arguments, i.e. it can accept NULL-complemented
table rows. This differs from assumptions made in Item_func::not_null_tables(), so add
Item_func_equal::not_null_tables().

calculated (and ignore it)
