heapam: Only set tuple's block once per page in pagemode Due to splitting the block id into two 16 bit integers, BlockIdSet() is more expensive than one might think. Doing it once per returned tuple shows up as a small but reliably reproducible cost. It's simple enough to set the block number just once per block in pagemode, so do so.
