[SPARK-9358][SQL][WIP] Code generation for UnsafeRow concat.
This patch creates a code generated unsafe row concatenator that can be
used to concatenate two UnsafeRows into a single UnsafeRow.
Note that this is still WIP. It doesn't yet handle data concat yet, but
only bitset (which is arguably the harder one).
You can merge this pull request into a Git repository by running:
