### What changes were proposed in this pull request? This PR adds `DecimalDivideBenchmark`, measuring per-row Decimal division (`select a / b`) for: - `decimal(7,2) / decimal(7,2)` — compact Long representation case - `decimal(38,18) / decimal(38,18)` — BigDecimal representation case - each shape also with an integer-literal divisor (`a / 2`, the TPC-DS q4 `year_total` shape), with ANSI mode off and on Divisors are generated non-null and `>= 1` so the divide-by-zero branch is not measured. ### Why are the changes needed?
