IMPALA-14094: Prepend to commit, refactor estimated table stats
IMPALA-14094 adds statistics for the Calcite planner. The row count
statistics for the original planner are estimated within HdfsScanNode
when the statistics are missing because they were not computed with
the compute statistics command.
This commit refactors this estimation code so that it is shareable.
