pgsql: Fix make_restrictinfo_from_bitmapqual() to preserve AND/OR

Log Message:
-----------
Fix make_restrictinfo_from_bitmapqual() to preserve AND/OR flatness of its
output, ie, no OR immediately below an OR. Otherwise we get Asserts or
wrong answers for cases such as
select * from tenk1 a, tenk1 b
where (a.ten = b.ten and (a.unique1 = 100 or a.unique1 = 101))
or (a.hundred = b.hundred and a.unique1 = 42);
Per report from Rafael Martinez Guerrero.
