BUG#727667 Wrong result with OR + NOT NULL in maria-5.3
- put the code that sets HA_NULL_PART bit back
- Fix test_if_ref/part_of_refkey() so that
= NULL-ability of lookup columns does not prevent the equality
from being removed (we now have early/late NULLs filtering which
will filter out NULL values)
= equality is not removed if it is ref_or_null access, and the value
of the lookup column can alternate between the lookup value and NULL.
