Log message:
    In _bt_check_unique() loop, don't bother applying _bt_isequal() to
    killed items; just skip to the next item immediately.  Only check for
    key equality when we reach a non-killed item or the end of the index
    page.  This saves key comparisons when there are lots of killed items,
    as for example in a heavily-updated table that's not been vacuumed lately.
    Seems to be a win for pgbench anyway.
