I added a new benchmark to count the number of valid int8 values in a random `struct<a: struct<b: int8>>` array. Due to the use of `CountSetBits` batch interface, `VisitTwoBitRunsVoid` achieves better performance than `VisitTwoBitBlocksVoid` in most cases. parent_null_every | value_null_every | BitBlocks ns | BitRuns ns | vs block | SetBitRuns ns | vs block -- | -- | -- | -- | -- | -- | -- 2 | 2 | 5100500 | 3247773 | 0.64x | 3272429 | 0.64x 2 | 8 | 4592000 | 3371095 | 0.73x | 3245095 | 0.71x 2 | 64 | 4338500 | 3281286 | 0.76x | 3272810 | 0.75x 8 | 2 | 4439125 | 3052261 | 0.69x | 3103000 | 0.70x 8 | 8 | 2801040 | 3075136 | 1.10x | 3090304 | 1.10x 8 | 64 | 2326967 | 3070955 | 1.32x | 3171870 | 1.36x 64 | 2 | 4132647 | 813513 | 0.20x | 848000 | 0.21x 64 | 8 | 2026114 | 835193 | 0.41x | 823469 | 0.41x 64 | 64 | 1456122 | 789952 | 0.54x | 842785 | 0.58x 512 | 2 | 3918444 | 100072 | 0.03x | 98034 | 0.03x 4096 | 2 | 3878944 | 26525 | 0.01x | 26539 | 0.01x 65536 | 65536 | 1052229 | 14449 | 0.01x | 14641 | 0.01x -- This is an automated message from the Apache Git Service.
