SPARK-22345: Fix sort-merge joins with conditions and codegen.
## What changes were proposed in this pull request?
This adds a joined row to sort-merge join codegen. That joined row is used
to generate code for filter expressions, which may fall back to using the
result row. Previously, the right side of the join was used, which is incorrect
(the non-codegen implementations use a joined row).
## How was this patch tested?
Current tests.
