Tom Lane 3f50ba27cf Create infrastructure for 'MinimalTuple' representation of in-memory ...

tuples with less header overhead than a regular HeapTuple, per my
recent proposal.  Teach TupleTableSlot code how to deal with these.
As proof of concept, change tuplestore.c to store MinimalTuples instead
of HeapTuples.  Future patches will expand the concept to other places
where it is useful.
