Description

Below three Jira tasks optimize bitmap operations(logical, copy, compare, etc) unaligned case. They use word-by-word approach instead of bit-by-bit to improve performance.
There are some common code of read/write bitmap in words. It's better to implement word based bitmap reader and writer to wrap similar function and reduce code redundancy.
