......................................................................
WIP IMPALA-14852 Codegen tuple copy for Broadcast Exchange
Use Tuple::TryDeepCopy in RowBatch/OutboundRowBatch instead of DeepCopy.
For most tuples, this should save an extra size calculation, because the
size of the whole row is not calculated anymore before the copying, only
if a tuple doesn't fit, is its size calculated.
A codegen'd version of Tuple::TryDeepCopy is used for each tuple in the
row, which is generated based on the Tuple's Descriptor.
