Use repalloc_huge() to enlarge a SPITupleTable's tuple pointer array.
Commit 23a27b039d94ba35 widened the rows-stored counters to uint64, but
that's academic unless we allow the tuple pointer array to exceed 1GB.
(It might be a good idea to provide some other limit on how much storage
a SPITupleTable can eat. On the other hand, there are plenty of other
ways to drive a backend into swap hell.)
