support full join for nested loop join

[crwen]

What problem does this PR solve?

Issue link: #206

Add support for nested loop join

Some results does not mathe sql statements(e.g. column numbers, results order) in join.slt, so I changed some results or sql.
And some sql may have wrong syntax, so I remain them commented.
