Remove obsolete cases from GiST update redo code.
The code that generated a record to clear the F_TUPLES_DELETED flag hasn'texisted since we got rid of old-style VACUUM FULL. I kept the code that setsthe flag, although it's not used for anything anymore, because it mightstill be interesting information for debugging purposes that some tupleshave been deleted from a page.Likewise, the code to turn the root page from non-leaf to leaf page wasremoved when we got rid of old-style VACUUM FULL. Remove the code to replaythat action, too.
