Use platform independent type for TupleTableSlot->tts_off.
Previously tts_off was, for unknown reasons, of type long. For onethat's unnecessary as tuples are restricted in length, for anotherlong would be a bad choice of type even if that weren't the case, asit's not reliably wider than an int. Also HeapTupleHeader->t_len is auint32.This is split off from a larger patch implementing JITed tupledeforming. Seems like an independent improvement, as tiny as it is.Author: Andres Freund
