Implement eytzinger0_find_ge() directly instead of implementing it in
terms of eytzinger0_find_le() and adjusting the result.
This turns eytzinger0_find_ge() into a minimum search, so when there are
duplicate elements, the result of eytzinger0_find_ge() will now always
point at the first matching element.
