While working on [1] I found an outdated comment in heap_page_is_all_visible() and two other small fixes.
0001: Updates that comment so future authors know that this "stripped down function" should retain the logic in heap_page_prune_and_freeze(), not lazy_scan_prune() as was the case before 6dbb490. 0002: Mimics the same loop logic as in heap_page_is_all_visible() so as to a) stay in sync and b) benefit from the mentioned CPU prefetching optimization. 0003: Moves the ItemSetPointer() just a bit further down in the function again to a) stay in sync and b) to sometimes avoid that tiny overhead.
