ARROW-8553: [C++] Optimize unaligned bitmap operations Unaligned bitmap operations are currently calculated bit-by-bit. Processing it word-by-word in uint64 improves performance significantly. BenchmarkBitmapAnd/32768/1 jumps from 56M/s to 4.1G/s on my test machine. This patch also improves unit test to cover new code thoroughly.
