Goal

• Replace copies with moves when passing callables between internal functions in <algorithm> and <numeric>. For callables which are expensive to copy, such as some specializations of std::function, this will avoid allocating memory or other costly operations.

Acceptance criteria

Close the upstream bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111963

Either a fix (with tests) should be committed upstream, or the bug should be closed with rationale for not making the change.
