Turn nonzeroing move hints back off by default.
This is a temporary workaround for the bugs that have been found in the implementation of PR #26173. * pnkfelix is unavailable in the short-term (i.e. for the next week) to fix them. * When the bugs are fixed, we will turn this back on by default. (If you want to play with the known-to-be-buggy optimization in the meantime, you can opt-back in via the debugging option that this commit is toggling.)
