Use PageIndexTupleOverwrite() within nbtree.
Use the PageIndexTupleOverwrite() bufpage.c routine within nbtree
instead of deleting a tuple and re-inserting its replacement. This
makes the intent of affected code slightly clearer. It also makes
CREATE INDEX slightly faster, since there is no longer a need to shift
every leaf page's line pointer array back and forth during index builds.
