enhance: [bitset] extend op_find() to be able to search both 0 and 1 ( #39176 )
...
issue: #39124
`bitset::find_first()` and `bitset::find_next()` now accept one more
parameter, which allows to search for `0` bit instead of `1` bit

enhance: [bitset] multiple 'and' and 'or' in a single op ( #33345 )
...
issue #34117
* Refactoring
* Added a capability to perform multiple bitwise `and` and `or`
operations in a single op
* AVX2, AVX512, ARM NEON, ARM SVE backed bitwise `and`, `op`, `xor` and
`sub` ops
* more unit tests for bitset
* fixed a bug in `or_with_count` for certain bitset sizes
* fixed a bug for certain offset values for inplace operations that take
two bitsets

enhance: Custom bitset and bitsetview prototypes ( #30454 )
...
Issue: #31285
Basically, I've replaced `FixedVector<bool>` and `boost::dynamic_bitset`
with custom bitset and bitsetview in order to reduce the memory
bandwidth & increase performance for the filtering.
This PR is for internal use only.
Current progress (numbers are for GCC 9.5.0 on Ubuntu 22.04 LTS;
clang-17 produces better performance numbers):
