Description
Make sure that for all algorithms specialized for vector<bool>, both std:: and ranges:: flavor is equally specialized.
Make sure all distinct code paths are tested.
Currently optimized:

Research direction
Start by comparing the existing std:: and ranges:: implementations for the listed vector algorithms: copy, count, fill, find, move, transform, and all_of/any_of/none_of. Trace each distinct code path and inspect the corresponding STL tests. Done means the optimization coverage is equivalent between both algorithm flavors and all distinct paths are tested.
